4-Dimethylaminopyridine (DMAP) has emerged as a versatile reagent for effecting acylation, 1,2 and its role as an efficient acyl transfer catalyst3 during the acylation of tertiary alcohols is particularly noteworthy. However, when we attempted to acetylate a P-hydroxycarbonyl compound using the protocol followed in the DMAP method,3 a mixture of the acetate and the a,@-unsaturated carbonyl compound was obtained (see Table 1). This may be owing to the basic medium ...
