The Photochemistry of Carbohydrate Derivatives. Part 7. The Synthesis of Methyl 3,4-Di-O-(β-D-glucopyranosyl)-α-L-rhamnopyranoside from Photolabile Methyl 2,3-O-(2-Nitrobenzylidene)-α-L-rhamnopyranoside

Methyl endo/exo-2,3-O-(2-nitrobenzylidene)-α-L-rhamnopyranoside (1) was glucosylated to give the fully protected β-(1->4)-linked disaccharide derivative (5) as an endo/exo mixture which, upon photolysis and oxidation gave, after chromatography, the partia
