Description

Pseudo-nucleoside compound of chirality and preparation method thereof and application
Technical field
The present invention relates to pseudo-nucleoside compound of chirality and preparation method thereof and application.
Background technology
Pseudo-nucleoside compound; Also claim the non-natural nucleoside compounds; Be one type of compound similar with natural nucleus glycoside on chemical structure, thereby can disturb or directly be used for the metabolic process of nucleic acid, the biosynthesizing of blocking protein, nucleic acid in vivo; Therefore, these compounds occupy an important position in antiviral and antitumor drug.
It is raw material that the compound of present pseudo-ucleosides mainly adopts the natural sugar compounds, synthesizes pseudo-nucleoside compound through the formation of glycosidic link.Wherein the selective control of glycosidic link is relatively more difficult.The present invention makes up cis or the trans false sugar ring of chirality skeleton earlier through the method for biocatalysis, has avoided the selective control of glycosidic link.
Biocatalysis is that up to now tool is efficient, highly selective and eco-friendly process, utilize the method for biocatalysis more synthetic have the chemical of high added value, particularly the chirality chemical has important application prospects and meaning.Nitrile is one type of important organic synthesis intermediate; The chemical conversion requirement condition harshness and the selectivity of nitrile are very poor; And the bioconversion reaction of nitrile has advantages such as mild condition, highly selective; Applicable industryization prepares corresponding carboxylic acid and amide derivatives at present, and foremost is to be taken the lead in realizing the industriallization of microbial method synthesis of acrylamide in 1985 by Japanese Nitto company (renaming Mitsubishi Rayon company as) at present.The YO of acrylic amide in 1998 surpasses 40,000 tons, becomes one of industrial biological path for transformation of present maximum-norm in the world.Rhodococcus Rhodococcus rhodochrous J1 also by Switzerland Lonza AG company in order to suitability for industrialized production vitamin B group vitamin PP and nicotinic acid, wherein the YO of vitamin PP is above 3000 tons.But form the reacting phase ratio with hydrolysis of enzyme catalysis ester and ester bond, the biocatalytic reaction of nitrile and acid amides is also less relatively.The bioconversion reaction of nitrile and acid amides can not only obtain carboxylic acid, and through kinetic resolution with go method of symmetrization can also obtain unavailable organic compounds containing nitrogen acid amides of ester hydrolysis reaction or nitrile.
Summary of the invention
The purpose of this invention is to provide pseudo-nucleoside compound of a kind of chirality and preparation method thereof and application.
