Abstract:  D-g/ycero-L-Glucoheptose and D-g/ycero-L-mannoheptose were obtained by oxidative decomposition of 1 -deoxy-1 -nitroalditols prepared by nitromethane synthesis with D-galactose. The aldoheptoses epimerize under catalytic action of molybdate ions giving an equilibrium mixture of D-glycero-L-glucoheptose and D-glycero-L-mannoheptose in a ratio 4 : 1. The epimerization reaction was applied for reciprocal preparation of both of the mentioned aldoheptoses.
