title: First crystallographic evidence for the formation of beta-D-ribopyranosylamine from the reaction of ammonia with of D-ribose.
abstract: Beta-D-Ribopyranosylamine was synthesized and characterized using analytical, spectral and single-crystal X-ray diffraction methods. The molecule exists in the chair form with the 4C(1) conformation. The beta anomeric form of C-1 is supported by the dihedral angles. The molecule exhibits both intra- and intermolecular hydrogen-bond interactions of the type O-H...O, Nz-H...O and C-H...O, and these are interconnected to each other to form chains.
