摘要：

Unsaturated 1,4-disaccharides are obtained in quite good yields by alkylation of ethyl alpha-O-Delta(2)-glycosides, having a leaving group at C-4, with various 1-hydroxycarbohydrates in the presence of a catalytic amount of palladium(0). The reaction is regio- and stereospecific for alpha-erythro enosides 3 and 5, and only stereospecific in the case of the beta-threo enoside 7, alkylation occurring at C-4 and C-2 in this case.
