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 pr

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 optically active N-alkyl-Psyn-2,3-dimethylpen
