Asymmetric conjugate additions have been investigated with enantiopure N-enoyloxazolidinones for efficient construction of syn and anti-1,3-dimethyl arrays on an acyclic carbon backbone. Reactions of Yamamoto organocopper species exhibit characteristics of double asymmetric induction resulting from influences of the 4-substituted chiral auxiliary and features of side chain stereochemistry.
已经用对映体纯的N-烯酰恶唑烷酮研究了不对称共轭物的添加,以在无环碳主链上有效地构建顺式和反-1,3-二甲基阵列。山本有机铜物种的反应表现出由4-取代的手性助剂的影响和侧链立体化学的特征引起的双重不对称诱导的特征。
