摘要

A series of acetonides (both terminal and internal isopropylidene acetals) have been deprotected under catalytic, neutral conditions to give their corresponding 1, 2-diols. The reactions utilize indium (III) triflate in the presence of water and an organic solvent with mild microwave heating. Terminal acetonides are chemoselectivley removed in the presence of internal acetonides; acid labile functional groups remain intact under these conditions, ...
