In the presence of silver tetrafluoroborate stannylated primary alcohols react with the a-D-gf/wco-epoxide 58 to give a-glycosides [42], When the acceptor is a glycal such as 63, an a-disaccharide glycal 64 is obtained, upon which the process can be reiterated to give a trisaccharide 65 (Scheme 14). [Pg.378]
