Abstract

Abstract The preparation of 3, 5-(R)-O-benzylidene-D-glycero-D-gulo-heptono-1, 4-lactone, a readily available and powerful chiron, is described; other benzylidene derivatives of heptono-1, 4-lactones are characterised. The X-ray crystal structure of 3, 5 (R): 6, 7 (R)-di-O- benzylidene-D-glycero-D-gulo-heptono-1, 4-lactone is reported.
