A simple and efficient method is developed for the chemoselective one-pot conversion of tetrahydropyranyl (THP) and methoxymethyl (MOM) ethers of primary alcohols to the corresponding acetates by indium triiodide-catalysed deprotection and subsequent acetylation by ethyl acetate through a transesterification process.

A totalsynthesis of the antimicrobial, structurally unusual sesterterpenoid (±)-palauolide (1) is described. Methylenecyclohexane annulation of 3,6-dimethyl-2-cyclohexen-1-one (4) afforded a mixture of the bicyclic ketones 7 and 9 in a ratio of 94:6. Stereoselective conversion of this mixture into the phosphorodiamidate 46 was achieved via a five-step reaction sequence. Reduction of 46 with Li in
