S -Glycosides: Synthesis of S -linked arabinoxylan oligosaccharides

S-Glycosides are important tools for the elucidation of specific protein-carbohydrate interactions and can significantly aid structural and functional studies of carbohydrate-active enzymes, as they are often inert or act as enzyme inhibitors. In this con

Total synthesis of the anticancer natural product OSW-1

The highly potent anticancer natural saponin OSW-1 has been successfully synthesized from commercially available 5-androsten-3β-ol-17-one 79 in 10 operations with 28% overall yield. The key steps in the total synthesis included a highly regio- and stereoselective selenium dioxide-mediated allylic oxidation of 80 and a highly stereoselective 1,4-addition of α-alkoxy vinyl cuprates 68 to steroid 17(20)-en-16-one 12E to introduce the steroid side chain. This total synthesis demonstrated once again the versatile synthetic applications of α-halo vinyl ether chemistry developed in our laboratories.

Synthesis of glycosides bearing the disaccharide of OSW-1 or its 1→4-linked analogue and their antitumor activities

Twelve glycosides bearing the disaccharide of OSW-1, namely 2-O-(4-methoxybenzoyl)-β-D-xylopyranosyl-(1→3)-2-O-acetyl-α-L-arabinopy ranosides, or its 1→4-linked analogue, were synthesized, and their antitumor activities were determined. (C) 2000 Elsevier Science Ltd.
