Abstract
2,3- 3,4-, and 4,6-O-Benzylidene pyranoside derivatives on photobromination in bromotrichloromethane yield bromo-deoxy-pyranoside benzoates regio- and stereo-specifically which, for the acyl derivatives of the 2,3- and 3,4-acetals, is superior to their reaction with N-bromosuccinimide.Keywords
