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,Ac_2O and Bz_2O in the presence of 1-methylimidazole is described.It was observed that auxiliary base,triethylamine,accelerates the acylation reaction.
