The sodium salt of 2,3,4,6-tetra-O-benzyl-D-glucono-1,5-lactone tosylhydrazone 4 has been prepared in two steps from 2,3,4,6-tetra-O-benzyl-D-glucopyranose (1). The possibility of using this salt as a glucosylidene carbene precursor has been demonstrated by synthesizing glucosylidene-spirocyclopropanes (2,3,4,6-tetra-O-benzyI-2′(or 3′)-cyano-1-deoxyspiro(D-glucose-1,1′-cyclopropanes]) via photolysis of 4 with acrylonitrile.
