A method of synthesizing a chiral compound having a quaternary carbon atom bearing diastereotopic groups from (a) a nitroolefin and (b) an α-substituted β-dicarbonyl or an equivalent compound having an acidic C—H moiety compound is disclosed. A subsequent intramolecular reaction between one of the substituents comprising the stereogenic carbon atom and one of the diastereotopic groups comprising the quaternary carbon atom creates a new compound having two contiguous stereogenic centers, one of which is quaternary, with control over the relative stereochemistry.
本发明公开了一种从(a)硝基烯烃和(b)α-取代的β-二羧基或具有酸性C-H官能团的等效化合物合成具有四元碳原子承载对映异构基团的手性化合物的方法。随后,由立体异构碳原子中的一个取代基与四元碳原子中的一个对映异构基团之一之间的分子内反应,创造了一个具有两个相邻的手性中心的新化合物,其中一个是四元的,并控制相对立体
