Selective 6-O-Debenzylation of Mono- and Disaccharide Derivatives Using ZnCl2-Ac2O-HOAc
摘要:
Freshly fused ZnCl2 in Ac2O/HOAc at room temperature has been used for 6-O-debenzylation of mono-and disaccharide derivatives giving yields more than 80%. Notably, allyl, acetyl, benzoyl, tosyl, thiono groups are unaffected under the designated conditions. (C) 1997 Elsevier Science Ltd.
