SYNTHETIC STUDIES ON CAPNELLOL FAMILY : AN IMPROVED SYNTHESIS OF Δ9(12)-CAPNELLENE-3β,8β,10α-TRIOL AND THE FIRST TOTAL SYNTHESIS OF Δ9(12)-CAPNELLENE-3β,8β,10α,14-TETROL

A much improved synthesis of Δ9(12)-capnellene-3β,8β,10α-triol and the first total synthesis of Δ9(12)-capnellene-3β,8β,10α,14-tetrol have been accomplished via the common synthetic intermediate 17.
