Abstract
Abstract A concise and efficient synthesis of (−)-10-epi-5β,11-dihydroxyeudesmane 1 and (−)-4,10-epi-5β,11-dihydroxyeudesmane 2, via (−)-10-epi-γ-eudesmol 5, was accomplished starting from (+)-dihydrocarvone. The salient feature of our synthesis is the utilization of substrate-directable epoxidation and homogeneous hydrogenation to control the stereochemistry at the C-4 and C-5 positions of the title compounds.
