Abstract
An improved process for acid-catalyzed acylation using water-tolerant Lewis acid catalysts is described. The method involves reacting a reduction products of 5-(hydroxylmethyl)-furfural (HMF), in particular either furan-2,5-dimethanol (FDM) or bis-2,5-(hydroxymethyl)-tetrahydrofuran (bHMTHFs), with an excess of an organic acid in the presence of a Lewis acid metal triflate at a temperature and time sufficient to produce esters. The conversions of the reduction products of HMF to corresponding diesters can be quantitative with certain favored Lewis acids catalysts.
