Riboflavin-2′, 3′-dibenzoate, riboflavin-4′, 5′-dibenzoate, riboflavin-2′, 3′-di-n-butyrate, riboflavin-4′, 5′-di-n-butyrate, riboflavin-2′, 3′-dinicotinate and riboflavin-4′, 5′-dinicotinate were prepared from the monoisopropylidene derivatives. Migration of acyl group was observed in the riboflavin-2′, 3′-diesters. Riboflavin-2′, 3′-diesters are hydrolyzed more rapidly than the 4′, 5′-diesters, whereas isopropylideneriboflavin-2′, 3′-diesters are hydrolyzed more slowly than the 4′, 5′-diesters by hog pancreatic lipase.
