A selective method for oxygen deprotection of bistrimethylsilylated ω-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 (>75percent).Comparisons are made between standart aqueous acid procedures and a series of resins.
