摘要

Compound 7, a key intermediate for the synthesis of (+)-1, was obtained from 4 in 71% yield by similar procedures. The hydroxyl group of 7 was easily removed by reducing 7 with NaBH4 and a stereoisomeric mixture of 8a and 8b was obtained in 69% yield. The stereochemistry of the 5-acetoxyl group of 7 was unknown, but the stereochemistry of 8 was found to mainly be trans (9: l). After each stereoisomer was separated by column ...
