A novel method for preparation of C-glycopyranosylmethanal oximes is described. Treatment of per-O-acetylated C-glycopyranosylnitromethanes of the β-D-gluco, β-D-manno, β-D-galacto, β-D-xylo, and β-L-rhamno configurations with tributyltin hydride and a catalytic amount of 1,1′-azobis(cyclohexanecarbonitrile) afforded the corresponding methanal oximes in isolated yields of 84-97%.
