Abstract
PURPOSE: To obtain the title substance useful as a raw material for the synthesis of pesticides and medicines, by reducing and dehydrobrominating 9α-bromo-10,13β- epoxy-13α-isopropyl-2,6,10β-trimethylcyclotetradeca-1,5-diene.
CONSTITUTION: One mole of a compound of formulaI is reduced and dehydrobrominated in the presence of about 4g equivalents of a metal, e.g. Zn or iron, in an aqueous alcohol, e.g. 50W95% ethanol, under heating at the reflux temperature of the solvent for 5W15hr to give cembrenol of formulaII.
EFFECT: The product having trans form double bonds introduced is the same as the naturally occurring substance and of great industrial value.
