Description
Technical Field
The invention belongs to the technical field of organic synthesis, and particularly relates to an alkyne derivative containing a nitrogen-oxygen bond, and a preparation method and application thereof.
Background
Alkyne has unique physical properties such as rigidity and optical properties and rich chemical properties such as the ability to carry out electrophilic addition, nucleophilic addition and Diels-Alder reaction simply and efficiently to build molecular complexity, and can also be subjected to click reaction (C)Click reaction) to complete the chemical synthesis of the color molecules rapidly and reliably. Even though alkynes are functional groups that are ubiquitous in the fields of materials, medicine, and the like. However, the existing alkyne synthesis method mainly relies on the coupling reaction of terminal alkyne catalyzed by transition metal to construct Csp2-the Csp bond, i.e. the majority still concentrated on alkene, arene-substituted alkyne compounds;
the prior art construction of alkyl-substituted terminal alkynes remains a significant challenge in the field of organic synthesis to date:
1) if the strategy of directly reacting alkyl halide with an alkynylation reagent is used for constructing the internal alkyne with alkyl at both ends, an alkyl metal catalyst species generated in situ by the alkyl halide is easy to generate rapid beta-H elimination reaction to obtain an olefin byproduct, so that target conversion is difficult to obtain;
2) this strategy has good step and atom economy if it is used directly to construct alkyl-substituted terminal alkynes using a strategy of reacting alkyl carbon-hydrogen bonds with alkynylating agents. However, consider the alkyl group Csp3The activity of the-H bond is very low and alkyl substrates usually contain a plurality of different kinds of alkyl Csp3-H bond, which also enables the exploration of the direct para-alkyl Csp3The direct, site-selective alkynylation of the-H bond remains a great challenge.
Prior art consists of a simple alkyl Csp3-H bond through Csp3Examples of strategies for the selective functionality of the-H bond for the construction of alkynes are very limited and mainly focus on the use of functionalities that are difficult to convert, or/and expensive to synthesize, such as amides of 4-trifluoromethyl-2, 3,5, 6-tetrafluoroaniline, amide derivatives of 8-aminoquinoline as guiding groups to promote Csp3-selective alkynylation of the H bond. Despite its good catalytic efficiency, the difficulty of converting or obtaining the directing group limits its wide application.
In summary, the efficient synthesis of alkyl alkynes, especially alkyne compounds containing functional groups that are easy to be converted, still needs to be further developed, and the types of alkyne derivatives are limited and need to be broadened.
Disclosure of Invention
In view of this, the present invention provides an alkyne derivative containing a nitrogen-oxygen bond, and a preparation method and an application thereof, for providing a new alkyne derivative containing a nitrogen-oxygen bond and widening the kinds of alkyne derivatives containing a nitrogen-oxygen bond.
The specific technical scheme of the invention is as follows:

wherein R is1And R2Independently selected from hydrogen, alkyl of C1-C20, aryl of C5-C30, substituted aryl of C5-C30 or aromatic heterocyclic radical of C5-C30, R3To replace silicon base.
The alkyne derivative containing the nitrogen-oxygen bond contains the nitrogen-oxygen bond which is easy to convert, can obtain primary amine with high added value and polysubstituted alcohol compounds containing alkynyl through reduction, and has good application prospect in the field of organic synthesis. In addition, the alkyne derivative containing the nitrogen-oxygen bond contains silicon base which is directly connected with the carbon-carbon triple bond of alkyne and can be conveniently detached, and a terminal alkyne compound can be further obtained.
In the invention, the alkyne derivative containing the nitrogen-oxygen bond can be converted into the alkynyl-containing alcohol compound simply, such as reduction by LAH (lithium aluminum hydride) and desilication by TBAF (tetrabutylammonium fluoride), so that the alkynyl-containing alcohol target product can be obtained quantitatively.

wherein,
R1and R2Independently selected from hydrogen, alkyl of C1-C20, aryl of C5-C30, substituted aryl of C5-C30 or aromatic heterocyclic radical of C5-C30, R3In place of the silicon group, X is hydrogen, bromine, chlorine, iodine or an iodine-containing heterocyclic group, preferably an iodine-containing heterocyclic group
The catalyst is a metal catalyst, and the metal of the metal catalyst is one or more selected from palladium, ruthenium, rhodium and iridium.
The existing alkyne synthesis method mainly relies on the coupling reaction of terminal alkyne catalyzed by transition metal to construct Csp2-Csp bond, such that the product is concentrated in olefin, arene substitutedAn alkyne compound. Based on a simple and easily obtained substrate, the rapid construction of the alkyne derivative containing the nitrogen-oxygen bond with important synthetic value through an efficient synthetic strategy still has great challenges. The reason is that: 1) the Sonogashira reaction starting from alkyl halides is often faced with in situ generated Csp3-the metal bond is susceptible to rapid β -H elimination to give an olefinic compound; 2) if directly with an alkyl group Csp3Construction of alkynes starting from H bonds, although having excellent step economics, such reactions are extremely challenging, on the one hand, the relatively flexible alkyl Csp3The high bond energy of H bonds makes activation of such inert chemical bonds very difficult; it is also noted that for a particular nitroxide bond-containing alkyl compound, it often contains a large and complex number and variety of Csp3-H bond, which allows activation of a specific Csp3the-H bond is extremely challenging; more importantly, the transition metal can catalyze the direct Csp of the alkyl alcohol by the side reactions such as oxidation (into ketone, aldehyde or carboxylic acid) and elimination (into olefin isomer) of the alkyl compound containing the nitrogen-oxygen bond under the oxidizing or alkaline condition3The selective functionalization of the-H bond remains a significant challenge in the field of organic synthesis to date.
To achieve inert alkyl groups Csp3Reactivity and selectivity of the functionalization reactions of H bonds, currently, the targeting strategy is widely applied to selective functionalization reactions of inert C-H bonds. However, the direct alkyl Csp promoted by a common targeting group (e.g., the professor of the Chinji's grant at the institute of Scripps USA uses a polyfluoroanilide-substituted amide compound as a targeting group, and the professor of Chatani's professor of the university of Osaka Japan uses an 8-aminoquinoline-derived amide as a targeting group)3The alkynylation of the-H bond, however, tends to be difficult or expensive to convert, which also makes the overall reaction process more difficult to put into practical use.
Even more challenging is the direct Csp for alkyl compounds containing nitroxide bonds3For the alkynylation of the-H bond, the side reaction of the conjugated diyne is greatly reduced because the Glaser reaction of an alkynylating reagent such as a terminal alkyne or a functionalized alkyne is very easy to occur under the catalysis of a transition metal so as to obtain the conjugated diyneThe formation takes place.
The compound shown in the formula (II) and the compound shown in the formula (III) are reacted under the action of a catalyst to obtain the alkyne derivative containing the nitrogen-oxygen bond shown in the formula (I), and the Csp of the compound shown in the formula (II) can be efficiently and highly selectively reacted3-H bond is subjected to an alkynylation reaction. In addition, the compound shown in the formula (II) and the compound shown in the formula (III) are widely applied to the fields of medicines, materials and the like, raw materials are common and easy to obtain, the obtained alkyne derivative containing the nitrogen-oxygen bond contains an easily-converted nitrogen-oxygen bond, primary amine with high added value and multi-substituted alcohol compounds containing alkynyl can be obtained through reduction, and the compound has a good application prospect in the field of organic synthesis.
The preparation method is based on metal catalysis, and Csp is directly carried out on the alkyl compound containing the nitrogen-oxygen bond3-H bond alkynylation having the following characteristics: 1) the preparation method of the invention directly uses inert Csp3An alkyne is constructed by starting from an H bond, so that the method has good atom economy and step economy and accords with the synthesis concept of green chemistry; 2) the silicon base is used as a substituent of alkyne, can be conveniently removed, and then terminal alkyne is obtained; 3) the product alkyne derivative containing the nitrogen-oxygen bond contains the nitrogen-oxygen bond which is easy to convert, and can further realize the high-efficiency synthesis of primary amine and polysubstituted alkynyl-containing alcohol compounds; 4) the chemical conversion of the preparation method has excellent position specificity, namely, the reaction generates a nitrogen-containing organic metal cyclic intermediate in situ, and then the nitrogen-containing organic metal cyclic intermediate is generated in the first-level Csp3And carrying out regioselective alkynylation reaction on the-H bond to obtain the alkyne derivative containing the nitrogen-oxygen bond.
The preparation method of the invention has the advantages of easy introduction and conversion of the nitrogen-oxygen bond of the alkyl compound based on the nitrogen-oxygen bond, avoids the problems of carbonyl compound or alkene byproduct and the like caused by easy elimination and oxidation side reaction in the catalytic oxidation of carbon-hydrogen bond functionalization reaction, solves the side reaction of oxidation, elimination and the like of the alkyl compound containing the nitrogen-oxygen bond, and provides a simple and efficient strategy for Csp of the alkyne compound containing the nitrogen-oxygen bond3-H bond for efficient transformation. Nitrogen in alkyne derivative containing nitrogen-oxygen bond obtained by preparation method of the inventionThe oxygen bond can be converted into the alcohol compound containing alkynyl and primary amine through reduction reaction, so that the alkyl compound containing the nitrogen-oxygen bond is converted into the alcohol containing alkynyl, and the nitrogen-oxygen bond is used as a traceless guiding group. The preparation method can realize the conversion of the five-membered metal cyclic intermediate containing nitrogen atoms through the regulation of a nitrogen-oxygen bond structure, thereby achieving the Csp of position selectivity3-an alkynylation of the H bond; and, the conversion is only applied to the first order Csp3-H bond reaction.
The preparation method has wide application range to the substrate, and the obtained position-selective alkyne derivative containing the nitrogen-oxygen bond is easy to convert subsequently and can directly carry out later modification on the alcohol derivative with potential biological activity.
