Stereoselective formation of glycosyl sulfoxides and their subsequent equilibration: Ring inversion of an α-xylopyranosyl sulfoxide dependent on the configuration at sulfur

Crich, David,Mataka, Jan,Zakharov, Lev N.,Rheingold, Arnold L.,Winkt, Donald J.

, p. 6028 - 6036 (2002)

A series of four S-allyl D-thiopyranosides, α- and β-manno and xylo, were oxidized with MCPBA at low temperature to give seven of the eight possible sulfoxides, whose configuration at sulfur was determined either directly by X-ray crystallography or by co
