(±)-7α-(1-Hydroxy-1-methylethyl)-4aβ-methyl-1aβ-decahydrocyclopropa[d]naphthalene, which was belived to be the structure of cycloeudesmol, was stereoselectively synthesized and was found to differ from cycloeudesmol.
Selective Allylic Hydroxylation of Octahydronaphthalene Derivatives with a Bridgehead Double Bond Using Electrochemical Method with Iron Picolinate Complexes
allylic hydroxylation of octahydronaphthalene derivatives. Substrates with a bridgeheaddoublebond gave the allylic alcohol with alpha-preference, while non-bridgehead olefin did not react smoothly. This system is a useful tool for alpha-selective allylic hydroxylation of octahydronaphthalene derivatives with a bridgeheaddoublebond as model compounds for the AB fused ring of cholesterols.
