SYNTHESIS, SPECTROSCOPIC STUDIES, AND X-RAY CRYSTALLOGRAPHIC ANALYSISOF THE ORGANOPHOSPHORUS CARBOHYDRATE - METHYL OXY-3-C-DIPHENYLPHOSPHINYL-ALPHA-D-ALTROPYRANOSIDE

The synthesis and molecular structure determination of an organophosph orus carbohydrate are reported. In the solid state the molecules of me thyl xy-3-C-diphenyl-phosphinyl-alpha-D-altropyranoside are linked tog ether by intermolecular hydrogen bonding involving the oxygen attached to phosphorus and the hydroxy group. The five-valent phosphorus atom is in a distorted tetrahedral environment. The chiral molecules crysta llize in the monoclinic space group P2(1) with Z = 2. Results from H-1 , C-13 and P-31 NMR investigations together with IR data are presented .
