Abstract

Acylation of sterically hindered alcohols is frequently encountered in synthetic chemistry. An efficient and mild procedure for tosylation and esterification of sterically hindered hydroxyl groups with p-TsCl, Ac₂O and Bz₂O in the presence of 1-methylimidazole is described. It was observed that auxiliary base, triethylamine, accelerates the acylation reaction.
