✦ Synopsis

Direct Synthesis of β-Mannopyranosides by the Sulfoxide Method.

-The activation of a glycosyl donor via the sulfoxide group followed by addition of a glycosyl acceptor in CH2Cl2 results in the formation of mannopyranosides in high yield and high β:α-ratios. Reducing the bulk of the O-2 protecting group leads to greater β:. alpha.-ratios for sec glycosyl acceptors. The very effective new method for the one-pot synthesis of the title compounds is generally applicable to a wide variety of prim and sec glycosyl acceptors. -(CRICH, D.;
