The synthetic utility of O-glycosylpseudourea derivatives for the preparation of glucosyl ethers and esters of amino acids and peptides (5, 6), and (1 → 6)- disaccharides (8) is reported. Simple two-step transformation of 1-O-unprotected sugars 1 is accomplished by a one-pot procedure giving products with high stereoselectivity in some cases.
