4-O-Benzyl-23-O-isopropylidene-L-threose: A useful building block for stereoselective synthesis of monosaccharides

4-O-Benzyl-23-O-isopropylidene-L-threose readily available from L-tartaric acid is a quite useful four-carbon building block for monosaccharide synthesis. The versatility can be reinforced by the coupled use of stereoselective addition reactions where the

A FORMAL TOTAL SYNTHESIS OF POLYOXIN J USING 4-O-BENZYL-2,3-O-ISOPROPYLIDENE-L-THREOSE AS A COMMON CHIRAL BUILDING BLOCK

A convergent formal total synthesis of Polyoxin J was achieved.Two fragments, deoxypolyoxin C and 5-O-carbamoylpolyoxamic acid, were synthetized in a highly stereoselective manner from the common chiral building block, 4-O-benzyl-2,3-O-isopropylidene-L-th
