Chiral pyrrolidinyl sulfonamides have been found to promote the conjugate additionâelimination reaction between activated allylic bromides and 1,3-dicarbonyl compounds with high enantioselectivities and the highly functionalised products can be used to generate a variety of interesting enantiomerically pure compounds via simple transformations.
手性吡咯烷基磺酰胺被发现能够促进活化的烯丙基溴化物和1,3-二酮化合物之间的共轭加成–消除反应,并具有高的对映选择性,生成的高官能化产物可以通过简单转化生成多种有趣的对映体纯化合物。
