MILD PROTECTION AND DEPROTECTION OF ALCOHOLS AS TER-BUTYL ETHERS IN THE FIELD OF PHEROMONE SYNTHESIS

Article abstract of DOI:10.1016/0040-4039(88)85055-X

α,ο-Halohydrins and ο-acetylenic alcohols are protected as t-butyl ethers by reaction with isobutene and an acid catalyst : Amberlyst H-15. t-Butyl ethers are, in turn, cleaved to acetates by Ac2O and 10 percent FeCl3 in Et2O solvent.Under these mild conditions conjugated dieneic systems are neither destroyed nor isomerized.
