Synthesis of diacylglycerol analogues as potential second-messenger antagonists and inhibitors of protein kinase C

4-O-Acetyl-3-O-tert-butyldimethylsilyl-l-rhamnal: a building block in the stereoselective synthesis of 2-deoxy-α-l-rhamnopyranosides

The stereoselective synthesis of 2-deoxy-alpha-L-glycosides by addition of various acceptors to 4-O-acetyl-3-O-tert-butyldimethylsilyl-L-rhamnal promoted by triphenylphosphine-hydrogen bromide is developed.

Regio- and stereoselectivity in preparation of 2-deoxysugar glycoglycerolipid derivatives evaluated by high resolution 1H NMR

New glycoglycerolipids, derivatives of 2-deoxysugars bearing one or two fatty acid chains have been synthesised. Various levels of regio- and stereoselectivity have been attained for the triphenylphosphine hydrobromide (TPHB) catalysed addition of the glycerol moiety to some representative glycals. The influence of the structure of glycal derivatives in glycosylation reactions is discussed.
