SYNTHESIS AND CONFORMATION OF 1,2,4-TRI-O-ACTYL-5,6-DIDOXY-3-O-METHYL-5-C-[(S)-PHENYLPHOSPHINYL]-β-d-GLUCOPYRANOSE

Abstract
Hydrolysis of phenylphosphinyl derivative of hexofuranose (1) followed by acetylation gave two compounds. The X-ray analysis of one component revealed the structure to be 1,2,4-tri-O-acetyl-5,6-dideoxy-3-O-methyl-5-C-[(S)-phenylphosphinyl]-β-d-glucopyranose (3a) which had a 4C1 (d) conformation.
