NOVEL DIASTEREOSELECTIVE ROUTES FOR THE SYNTHESIS OF THE AMBERGRIS KETALS

Maria do Céu Costa; Regina Tavares; William B. Motherwell; Maria João Marcelo Curto

New processes have been developed which allow the stereoselective syntheses of the ambergris ketals 8 alpha,13;13,17-diepoxi-14,15-dinorlabdane 1 and 8 beta,13;13,17-diepoxi-14,15-dinorlabdane 2, through selection of the appropriate catalyst for the delta,epsilon-epoxycarbonyl rearrangement of the key intermediate 3, which is, in turn, obtained by controlled oxidation of anticopalic acid 6.

Selective Ring-Opening of An Epoxide on Silica Supports

Maria do Céu Costa; Regina Tavares; Maria João Marcelo Curto; William B. Motherwell

Abstract The intramolecular δ,ɛ-epoxycarbonyl rearrangement of 8α,17-epoxy-14,15-dinorlabdan-13-one I to give stereoselectively two diastereoisomeric ketals II or III was promoted in heterogeneous media using silicic porous solids as catalysts, making possible to choose a convenient selective system through an adequate combination of solvent, catalyst and temperature.
