Article abstract of DOI:10.1016/S0008-6215(00)88053-2

A series of 2-O-benzoyl-4,6-di-O-benzyl-α-D-galactopyranosyl halides carrying either a second benzoyl group (8a, 12a) or a selectively removable, temporary protecting group (8b-d, 12b) at position 3 was synthesized from allyl α-D-galactopyranoside (1).The
