The use of certain types of atropisomeric amides, incorporating an N-MEM-ortho-tert-butylaniline group, for stereoselective reactions, has been explored. Enolate reactions of these systems are highly diastereocontrolled, and enantiomerically enriched starting materials can be obtained, starting from lactic acid, via a new SmI2 mediated reduction process.
已探索某些类型的对映异构酰胺的使用,这些酰胺包含N-MEM-邻位叔丁基苯胺基团,用于立体选择性反应。这些体系的烯醇反应具有高度的非对映体选择性,并且可以通过新的SmI2介导的还原过程,从乳酸出发获得富含对映体的起始材料。
