Formaldehyde dialkylhydrazones smoothly add to sugar aldehydes without any need of promoter or catalyst. α-Hydroxy dialkylhydrazones, which are obtained in good yields and high stereoselectivities, have been successfully transformed in cyanohydrins by treatment with magnesium monoperoxyphtalate (MMPP) and in O-protected α-hydroxy aldehydes by ozonolysis or HCl mediated hydrolysis. No racemization was observed in the cleavage of the dialkylhydrazone group.
Iterative, Stereoselective Homologation of Chiral Polyalkoxy Aldehydes Employing 2-(Trimethylsilyl)thiazole as a Formyl Anion Equivalent. The Thiazole Route to Higher Carbohydrates

A new approach to long-chain sugars is demonstrated by the stereoselective conversion of D-glyceraldehyde acetonide (2a), L-threose acetonide (2b), and dialdogalactopyranose diacetonide (2h) into higher homologues up to C9, C7, and C

Catalytic osmylation of (E)-6-O-benzyl-7,8-dideoxy-1,2:3,4-di-O-isopropylidene-α-D-glycero-D-galacto-non-7-enopyranose (15) proceeded with good stereoselectivity to give a mixture of 6-O-benzyl-1,2:3,4-di-O-isopropylidene-β-L-lyxo-D-galacto-nonopyranose (
