Regioselective Acylation of 1,4:3,6-Dianhydro-D-glucitol

, p. 174 - 176 (1987)
Acylation of 1,4:3,6-dianhydro-D-glucitol with anhydrides in the presence of heavy metal salts affords 5-endo-acylates with high regioselectivity, without detectable amounts of the isomeric 2-acylates.Acyl group migration occurs with preference for the 2-exo-position, on heating an acylation mixture, which contains varying amounts of 1,4:3,6-dianhydro-D-glucitol, 2- and 5-monoacylate and 2,5-diacylate, in the presence of reesterification catalysts and whilst distilling off the lower boiling 2-acylate.

Esterification of 1,4:3,6-dianhydro-D-glucitol (1) with carboxylic acids in the presence of 4-dimethylaminopyridine and dicyclohexylcarbodiimide affords 2-exo-acylates 3 with high regioselectivity, in addition to small amounts of the isomeric 5-endo-acylates 4 and 2,5-diacylates 5.
