amides have stable planar chirality at ambient temperature. The transformation of the enantiomerically enriched amides provides optically active compounds containing stereogenic centers in a stereospecific fashion. As a demonstration of the synthetic utility of the amides, we have synthesized (+)-γ-lycorane using such an optically active amide as a chiral building block.
已开发出一种具有多种取代基的九元二烯丙基环状酰胺的有效方法。合成的酰胺在环境温度下具有稳定的平面手性。对映体富集的酰胺的转化以立体特异性方式提供了包含立体中心的旋光化合物。为了证明酰胺的合成效用,我们使用这种光学活性酰胺作为手性结构单元合成了 (+)-γ-lycoran。
