Description
Technical Field
The invention belongs to the technical field of compound synthesis, and particularly relates to a preparation method of chiral dihydrochromone-2-carboxylic acid compounds and derivatives thereof.
Background
The dihydrochromone compound and the derivative thereof are widely existed in natural products and medicinal active molecules, and have wide pharmacological activities of antitumor, antibacterial, antidiabetic, antioxidant, anti-inflammatory, neuroprotective and the like. In addition, the compounds can also construct compound molecules with novel structures through chemical reactions with rich carbonyl groups, such as reduction to alcohol to obtain chromogen alcohol, reduction to methylene to obtain benzopyran skeleton, oxime formation with hydroxylamine, and the like, and series reactions derived from substituent groups on the skeleton, provide chemical entities for innovative drug research, and have important values in the field of organic synthesis and pharmaceutical chemistry research. The following formula lists some representative bioactive dihydrochromones and natural products and drug molecules derived therefrom.
The thiodihydrochromone and dihydroquinolinone compounds are analogs of dihydrochromone, and although the content of the compounds in natural products is less than that of the dihydrochromone compounds, the compounds have been reported to have wide pharmacological activity and even higher activity compared with the dihydrochromone compounds.
At present, although there are a lot of reports related to the synthesis of dihydrochromone, the stereoselectivity example is relatively limited. Among the existing methods for synthesizing chiral dihydrochromone compounds, the method for obtaining optically pure dihydrochromone by asymmetric catalytic hydrogenation of C2 or/and C3 substituted chromone compounds is the most direct and efficient method. The asymmetric catalytic hydrogenation reaction catalyzed by the transition metal has the advantages of high atom economy, environmental protection, simple and convenient operation and the like, and occupies an important position in academia and industry. In 2013, Glorius et al reported asymmetric reduction of C2 substituted chromone compounds catalyzed by chiral ruthenium azacarbene complexes (Ru-NHC), wherein the chromone compounds are completely reduced into protophenol compounds under the catalytic system, and secondary alcohols are selectively oxidized by PCC to obtain optically pure dihydrochromone compounds at C2. The method has wide substrate applicability, high yield, and enantioselectivity up to 91%ee。
In the same year, Metz task group reports a method for preparing optically pure dihydrochromone compounds by dynamic resolution catalyzed by chiral metal complexes. Taking a rhodium (III)/diamine complex as a catalyst, and obtaining the dihydrochromone and the chromanol through asymmetric hydrogen transfer reaction in the presence of formic acid and triethylamine. They also utilize the catalytic system to synthesize a prenyl dihydrochromone with pharmacological activity.
In 2017, Wanjun task group realizes the asymmetric reduction reaction of a copper complex hydrosilation catalyst for catalyzing C2 substituted chromone compounds to obtain a series of chiral dihydrochromone compounds, the reaction takes hydrosilation as a hydrogen source, and a non-noble metal catalyst is adopted, so that the influence on the environment is small, and certain advantages are achieved. In addition, the catalytic system also obtains excellent reaction results in the synthesis of the thiodihydrochromone. However, the high amount of catalyst used (up to 20 mol%) limits its industrial application.
In 2018, zhangwan bin subject group adopts self-developed RuPHOX-Ru complex catalyst to catalyze asymmetric reduction of C2 substituted chromone, chiral chromanol is obtained with chemical yield as high as 99%, diastereoselectivity of >20:1 and stereoselectivity of 99%, and chiral dihydrochromone compounds are obtained by oxidation in the presence of PCC. Furthermore, they also showed by control experiments that the reaction underwent a continuous hydrogenation process of the C = C and C = O double bonds.
The above catalytic systems all achieve excellent catalytic effects, but have certain problems, for example, the catalytic systems reported by glorious and zhangwan bin do not have functional group selectivity for the reduction of chromone compounds, and all directly obtain chiral chromanol, and the dihydrochromone compounds can be obtained through oxidation reaction. In addition, in the reported examples of asymmetric reduction, the substituent at the C2 position is mainly alkyl or aryl, and only the catalytic system developed by the Wanjun subject group tries to reduce two cases of chromone compounds substituted by ester groups at the C2 position. In fact, however, the introduction of the C2 reactive functional group (such as carboxyl, ester group, cyano, etc.) is beneficial to the further derivation and enrichment of the chiral dihydrochromone skeleton, so as to be more widely used in organic synthesis and innovative drug research. Therefore, the catalytic system reported by the invention has obvious advantages in view of the above two problems of the existing catalytic system.
