Abstract
A selective method for oxygen deprotection of bistrimethylsilylated o-alkynols is described using sulfonic acid type exchange resins in ether solvent. The method offers the advantages of selectivity toward the silicon-oxygen bond, easier monitoring of the reaction and workup, and higher yields (> 75%). Comparisons are made between standard aqueous acid procedures and a series of resins.
