1,2:3,4-di-O-isopropylidene-D-galactopyranos-6-yl-(N-diphenylmethylene )-glycinate 3, was prepared via a trans-esterification process from ethyl (N-diphenylmethylene)-glycinate and 1,2:5,6-di-O-isopropylidene-D-glucofuranos-3-yl-(N-diphenylmethylene) glycinate 9, via a trans-imination reaction from 1,2:5,6-di-O-isopropylidene-D-glucofuranos-3-yl glycinate 6 and diphenyl-ketiminium chloride.
