Document Type and Number:
WIPO Patent Application WO/1991/008187
Kind Code:
A1
Abstract:
A novel open-chain terpene compound useful as an intermediate for sarcophytol A having a resistance to a carcinogenesis and an antitumor activity and represented by general formula (I), wherein R1 is a hydrogen atom, a 1-alkoxyalkyl group, a tetrahydrofuryl group, a tetrahydropyranyl group or an acyl group, R2 is -CHO, -CH2OR3 or (a), wherein R3 is a hydrogen atom, a 1-alkoxyalkyl group, a tetrahydrofuryl group, a tetrahydropyranyl group or an acyl group, R4 is an alkyl group having 1 to 4 carbon atoms, provided that R1 and R3 are not simultaneously the same substituents and, when R1 is a hydrogen atom, R3 is neither an acetyl group nor a tetrahydropyranyl group and, when R2 is a group represented by formula (a), R1 is not a hydrogen atom.
