Regio- and Stereo-selective Synthesis of Peracetylated Carbohydrate Esters of Aromatic Fatty Acid Using p-Toluenesulfonic Acid as Catalyst

This paper describes an efficient synthesis of carbohydrate fatty acid esters based on a highly stereo- and regio-selective esterification. The suitably protected glycosyl was esterified with stearic acid to give mainly the beta-anomer in good yield using p-toluenesulfonic acid as catalyst. The structures of these compounds were fully confirmed by H-1, C-13 NMR, mass spectra and HRMS.
