A catalytic synthesis of novel 4-linked C-glycosyl coumarins was achieved using a dominoHeckreaction/lactonization process. Methyl 3-glycosyl cinnamates were prepared from methyl 4-glycosyl-but-2-enoates using a panel of aryl iodides under Heck conditions. A direct application of this new methodology was made toward preliminary hemagglutination inhibition assays against galectins-1 and -3. C-Galactoside
