β-Acarbose. VIII the synthesis of some N-linked carba-oligosacchandes

Two carbohydrate triflates have been used to alkylate a 1-epivalienamine derivative to give small amounts of the desired secondary amines, in addition to amounts of the products of elimination. Deprotection of the secondary amines afforded a carba-disacch
