M. Valpuesta et al., REACTION OF MONOSACCHARIDE DERIVATIVES WITH STABILIZED SULFUR YLIDES - A HIGHLY STEREOSELECTIVE SYNTHESIS FOR C-GLYCOFURANOSIDES, Tetrahedron, 49(42), 1993, pp. 9547-9560
Stereoselectivity in the formation of glycidic amides by reaction of v
arious aldehydo- and keto-sugars [(1), (4), (6), (8), (10) and (12)] w
ith N,N-dimethyl-2-(dimethylsulfuranylidene)acetamide (2) was studied.
The reaction with derivatives of reducing cyclohemiacetalic monosacch
arides (14) and (21), gives to alpha-C-glycofuranosyl-2(S)-hydroxyacet
amides with a higher yield and stereoselectivity.
