摘要

Sunmary: The dihydrox. yaldeh, yde 1, an important intermediate for the synthesis of moxylated vitamin D derlvatives via the corresponding tachysterol precursors, was prepared from (S)-(+)-carvone(5). The sequence involves as central step, the decarbox-, ylation and rearrangement of the epox. yql, ycidic acid 15, prepared from carvone oxide z.
