[摘要]：An efficient approach to 9-membered diallylic cyclic amides having a variety of substituents was developed. The synthesized amides have stable planar chirality at ambient temp. The transformation of the enantiomerically enriched amides provides optically active compds. contg. stereogenic centers in a stereospecific fashion. As a demonstration of the synthetic utility of the amides, the authors synthesized (+)-g-lycorane using such an optically active amide as a chiral building block.
