Starting from (R)-(+)- and (S)-(-)-pulegone, enantiomeric pairs of esters and lactones with the p-menthane system were obtained. The Claisen rearrangement of allylic alcohols and iodolactonization of gamma,delta-unsaturated acids were the key steps of syntheses presented. The structures of compounds were determined by both spectroscopic and crystallographic methods. Some of the synthesized compounds
从(R)-(+)-和(S)-(-)-普乐酮开始,得到具有对-薄荷烷体系的酯和内酯的对映体对。烯丙基醇的克莱森重排和γ,δ-不饱和酸的碘内酯化是提出的合成的关键步骤。化合物的结构通过光谱和晶体学方法确定。一些合成的化合物的特征在于令人感兴趣的气味性质。
