Cyclization of trans-β-monocyclohomofarnesic acid and the related compounds was closely examined in order to elucidate the reaction mechanism.It was revealed that the cyclization of trans-β-monocyclohomofarnesic acid proceeds via formation of the cationic intermediate followed by concerted lactonization to give trans-anti-trans norambreinolide stereoselectively.

Synthesis of norambreinolide by acid-catalized cyclization of trans-β-monocyclohomofarnesic aicd was studied.From the acid norambreinolide was obtained in 57 per cent by catalysis of stannic chloride in dichloromethane at -78 deg C.Isomerization of norambreinolide to norisoambreinolide was observed with a rise of reaction temperature in the presence of stannic chloride.
