Abstract
Acetylation of carbonyl compounds is generally achieved via reduction followed by the acetylation. In addition, the combination systems of borohydrides have been also reported for one-pot reductive acetylation of carbonyl compounds. In this context, reductive acetylation of carbonyl compounds as a key synthetic protocol is a straightforward method for conversion of carbonyl compounds to the coressponding acetates. Reductive acetylation of a variety of carbonyl compounds such as aldehydes, ketones and á,â-unsaturated enals/enones was carried out efficiently with sodiumborohydride /copper dimethylglyoxime, Cu(dmg)2, in ethyl acetate under reflux condition. The corresponding acetates were obtained in high to excellent yields.
