Description
Technical Field
The application belongs to the technical field of organic chemical synthesis, and particularly relates to an axial chiral alkenyl-sulfur ylide compound and a preparation method thereof.
Background
Sulfur ylides (s-ylides) have a carbanion structure stabilized by an adjacent positive sulfur ion; sulfur ylide is a functional group that can undergo multiple transformations, and due to its poor stability, it is generally introduced at the alpha position of the ketocarbonyl group to act to stabilize the functional group. As the interest of chemists on sulfur ylide increases, it has a significant impact on the fields of medicinal chemistry, material chemistry, chemical biology, biochemistry, etc.
Because rotation around a single bond is hindered, a group of conformational isomers can be separated from each other, forming new chemical species, which are atropisomers (atropimers) of each other. As atropisomers become more prevalent throughout drug discovery, there is an increasing opportunity to use atropisomers to modulate the potency, selectivity, and even pharmacokinetics of lead molecules in many classes of targets. Therefore, the novel atropisomer skeleton is developed, the asymmetric synthesis is realized, a more comprehensive axial chiral molecular library is established, and a wider visual field is very likely to be provided for the research and development of the atropisomer drugs.
