title = "Synthesis and stereochemical analysis of dynamic planar chiral nine-membered diallylic amide: Significant substituent effect on stereochemical stability",
abstract = "C4-Methyl substituted nine-membered diallylic cyclic amide 1ac was synthesized. HPLC analysis using a chiral stationary phase revealed the presence of isolable enantiomers, whose absolute stereochemistry were determined by X-ray analysis. Studies on the stereochemical stability of 1ac showed that its chirality is more labile than that of the non-substituted congener 1aa and C3-methyl substituted congener 1ab.",
