Abstract

Amino alcohol-derived acyl-transfer catalysts are shown to operate by an O-nucleophilic mechanism, and catalysts bearing electron-withdrawing groups in proximity to the hydroxyl group are found to be more active. This is attributed to an increase in the acidity of the hydroxyl group of the catalyst.
