Enantioselective synthesis of Hagen's gland lactone is described. The enantiomerically enriched diol was prepared by organocatalytic α-oxidation of the aldehyde. The other key reactions involved a highly diastereoselective intramolecular cyclopropanation of vinylogous carbonates to furnish donor–acceptor-substituted cyclopropanes and their ring opening and iodolactonization followed by reduction.
描述了哈根腺内酯的对映选择性合成。对映体富集的二醇是通过醛的有机催化 α-氧化制备的。其他关键反应涉及乙烯基碳酸酯的高度非对映选择性分子内环丙烷化,以提供供体-受体取代的环丙烷及其开环和碘内酯化,然后还原。
