Abstract: A process for the accelerated reduction of organic ester substrates by reacting with an amine borane, sulfide borane or ether borane complex as a borane source in the presence of organic accelerator compounds containing both Lewis acidic and Lewis basic sites in their structure, of which the Lewis acidic site can coordinate with the carbonyl group of the substrate and the Lewis basic site can coordinate with the borane wherein the organic accelerator compound contains a structural element of the formula N-B or is an oxazaborolidine or cyclic compound containing a structural element of the formula N-B-O where N- and O- are connected by a carbon chain or is derived from secondary amino alcohol via reaction with boranes or borates and wherein the esters are reduced to give alcohols.
