(formula presented) The 1,4-conjugate additions of a variety of organocopper reagents to some 4-O-crotonyl derivatives of methyl α-D-glucopyranoside proceeded with a high level of diastereochemical induction to provide the adducts carrying a β-substituted
Efficient and stereoselective synthesis of methyl 3-O-(3,6-anhydro-β-D-galactopyranosyl)-α-D-galactopyranoside and methyl 3,6-anhydro-4-O-β-D-galactopyranosyl-α-D-galactopyranoside
