Description
Technical field
The invention belongs to technical field of organic synthesis, and in particular to a kind of synthetic method of asymmetric conjugation diine.
Background technology
Conjugation diyne is the important source material and intermediate of organic synthesis field, and starting material can be used as big for synthesizing
Annulene, conjugation alkynes oligomer etc..Meanwhile or a variety of natural products and the skeleton structure with bioactive compound.Contain
There are some compounds of 1,3- diine structures to be determined high efficiency anti-tumor, antibacterial, anti-inflammatory and HIV-resistant activity.Such as:From
19 carbon diacetylenic acids of traditional Chinese medicine ingredient 19- (2- furyls) -5,7- separated in Artemisia capillaris etc..
The method for the asymmetric conjugation diine of synthesis reported in document is mainly the following:
(1) 2000 year E.Negishi seminar synthesizes asymmetric 1,3- conjugation two using Pd catalysed cross coupling selectivities
Alkynes.
Although the experimental method yield is higher, but needs a point three steps ability synthesis of conjugate diine, reaction is more complex.
(2) 2008 years Lei seminars report the synthesis of the asymmetric conjugation diine of palladium chtalyst.The reaction is with bromobenzene
Acetylene and end-group alkyne are substrate, Pd (dba)2For catalyst, a kind of alkenyl phosphine is ligand, and triethylamine is organic weak base, and is added
CuI makees co-catalyst.
The applicability of the reaction substrate is wider, has good selectivity, yield higher.But the method has used noble metal to urge
Agent and Phosphine ligands, synthesis cost are high.
(3) 2009 years, Lei seminars were on the working foundation of early period, by the way that NiCl is added2·2H2O makees catalyst and adds
Enter CuI and make co-catalyst, is equipped with TMEDA complexings, enabling obtain the cross-coupling products of higher yields.
Bimetallic catalyst is not used only in the experimental method, and TMEDA ligand complex is added, and reaction needs one kind
Alkynes is excessive.
(4) 2012 years Ranu synthesize asymmetrical diine using the complex-catalyzed cis- bromostyrenes of Cu-HAP.Herein
In reaction, trans-styryl bromide generally yields trans- eneyne product, and cis- styrene bromide is produced by elimination reaction
The cross-coupling of raw alkynes and another alkynes, generates two acetylene compounds of conjugation.
The experimental method utilizes the copper complex of specific structure, the synthesis of this complex more complex.
(5) 2013 years Xie Meihua seminars reported for work nickel catalysis alkyl Grignard reagent and alkynyl sulfone cross-coupling it is anti-
Asymmetric 1,3 diines should be synthesized.In the synthesis, Isosorbide-5-Nitrae-diaryl 1,3- diines can obtain moderate to good yield, and right
It is relatively low (30-54%) in alkyl-substituted 1,3- diines yield.
The alkyl Grignard reagent that the experimental method uses is not unstable, easy to operate.
(6) 2014 years Ranu seminars, without ligand catalyst, pass through Cs using bimetallicp-CspCoupling synthesis is asymmetric
1,3- diines.
The experimental method substrate wide adaptability, but used bimetallic catalyst.
In conclusion the method for prior art synthesis of conjugate diine is although more, but these methods some need by compared with
For complicated synthesis step;The reactant of some is unstable, and operation has certain difficulty;Some reaction time are long, and
Reaction yield is relatively low;Some easily cause environmental pollution using organic phosphine drug.More importantly this kind of reaction mostly uses palladium, nickel
Equal noble metals or bimetallic are catalyst, and reaction cost is not costly and recyclable, is not suitable for industrial production.
Therefore it provides a kind of novel method for synthesizing of asymmetric conjugation diine is necessary.
Invention content
The purpose of the present invention is to provide a kind of synthetic methods of asymmetric conjugation diine, make protection gas using argon gas, receive
The cis- alkene bromine of rice copper oxide catalyzation and end-group alkyne directly react the asymmetric conjugation diine of preparation, and synthetic method is at low cost, and raw material is easy
, operation is more convenient, and efficient, use scope is wide, is suitble to a variety of substrate reactions, and catalyst being capable of recycling.
A kind of synthetic method of asymmetric conjugation diine provided by the invention, includes the following steps:
A, after catalyst being mixed with Phen and highly basic, be added in argon atmosphere cis- alkene bromine, end-group alkyne with it is molten
Agent is stirred at reflux reaction 20-24h under conditions of 140-150 DEG C;
B, product obtains asymmetric conjugation diine by column chromatographic isolation and purification after extraction, drying, concentration.
Cis- alkene bromine in step A, end-group alkyne, catalyst, highly basic, Phen molar ratio be 1:1.2-1.5:0.05-
0.1:2-2.5:0.15-0.2.
