An efficient regioselectivesynthesis of 2-O-acyl-3-O-(1-acyloxyalkyl) prodrugs of vitamin C 5,6-acetonide has been developed which does not involve tedious column chromatographic separation of the desired products from contaminants exhibiting very similar Rf values. Vitamin C 5,6-acetonide is first acylated with one equivalent of acyl halide in the presence of two equivalents of pyridine. The crude
