The enantioselective synthesis of three structurally distinct classes of lignan from a single, aza-Claisen-derived, chiral morpholine amide is reported. The class of lignan formed is dependent on the substitution pattern in the aryl rings and choice of protecting group on a key benzylic hydroxyl group. The methodology has been used to asymmetrically synthesize and determine the absolute stereochemistry
Aza-Claisen rearrangement of enolates of N-alkyl-N-(2E)-butenylpropanamides with chiral alkyl groups proceeded with high relative asymmetric induction as well as excellent internal asymmetric induction to give opticallyactive N-alkyl-Psyn-2,3-dimethylpent-4-enamides.
具有手性烷基的N-烷基-N-(2 E)-丁烯基丙酰胺的烯醇酸酯的Aza-Claisen重排以较高的相对不对称诱导以及出色的内部不对称诱导进行,从而得到旋光的N-烷基-P syn -2,3 -二甲基戊-4-烯酰胺。
