Inhoud:
Ring-opening reactions of methyl 2,3-N-acetylepimino-4,6-O-benzylidene-2,3-dideoxy-α-D-mannopyranoside (2) and-α-D-allopyranoside (4) with phosphorodithioic acids 5 and 6 proceed smoothly at ambient temperature to give exclusively products of altro configuration in quantitative yields. A similar stereoselective reaction between methyl 4,6-O-benzylidene-2,3-dideoxy-2,3-epimino-α-D-mannopyranoside (1 and -α-D-allopyranoside (3) and the alkylammonium salt of the acid 6 requires more vigorous conditions.
