Starting from (R)-(+)- and (S)-(−)-pulegone enantiomeric pairs of hydroxy lactones and keto lactones were obtained by Claisen rearrangement of cis-pulegols and lactonization of epoxy esters. The hydroxy lactones were reduced with LiAlH4 in order to assign the configuration of the chiral centers. The structures of the synthesized compounds were established on the basis of spectroscopic and crystallographic
从 (R)-(+)- 和 (S)-(-)-pulegone 对映体对羟基内酯和酮内酯对通过顺式-pulegols 的 Claisen 重排和环氧酯的内酯化获得。羟基内酯用 LiAlH4 还原以分配手性中心的构型。合成化合物的结构是在光谱和晶体学数据的基础上建立的。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
