AnomericO-arylation and O-hctarylation of tetra-O-bcnzyl-, tctra-O-acctyl-, and O-unprotected glucose (1a-c) can be directly performed with electron dcficienl aromatic and hctcroaromatic systems having fluoro- (2A-2F) or phenylsulfonyl (3B, 3G-3K), respectively, as leaving groups. The reactions were carried out in DMF as solvent at room temperature with NaH as the base; they led in the products 4
