The Reaction of N-Dichloromethylene-N,N-Dimethylammonium Chloride (Viehe's Salt) with Methyl 4,6-O-Benzylidene-α-D-glucoside. An Alternative Synthesis of Methyl 4,6-O-Benzylidene-α-D-alloside

The reaction of methyl 4,6-O-benzylidene-α-D-glucoside with N-dichloromethylene-N,N-dimethylammonium chloride (Viehe's salt) in the presence of a base gives a mixture of carbamates (with triethylamine) or the 2,3-carbonate mainly (with pyridine).The treat

The Reaction of N-Dichloromethylene-N,N-dimethylammonium Chloride (Viehe's Salt) with Some Carbohydrate Diols

The reaction of Viehe's salt (Me2N1+=CCl2Cl1-) with various carbohydrate diols (manno, allo) in the presence of a base is reported, the products being, after hydrolysis, either carbonate (with pyridine) or the carbamate (with triethylamine).A rationalization of the two different types of product formed is given in terms of the stereoelectronic control proposal by Deslongchamps.
