Abstract

Oxidative glycosylations of the d-xylose-based oxepine 1,6-anhydro-3,4,5- tri-O-benzyl-2-deoxy-d-xylosept-1-enitol (1) using N-iodosuccinimide (NIS) are reported. The reaction produced 2-deoxy-2-iodo-α-d-idoseptanosides and 2-deoxy-2-iodo-β-d-guloseptanosides 2-9 in good yields. When limited equivalents of a glycosyl acceptor were used, or in the absence of a glycosyl acceptor, an intramolecular cyclization predominated to form 1,6-anhydro-3,4-di-O-benzyl-2-deoxy-2-iodo-Iα-d-idopyranose (10).
