  • Stereochemical control in radical cyclization routes to N-glycosides: role of protecting groups and of the configuration (E versus Z) of the acceptors
    作者:Jong Uk Rhee、Brian I. Bliss、T.V. RajanBabu

    The first radical intermediate in the thiourethane-mediated deoxygenation of an alcohol (Barton-McCombie reaction) can participate in an exo-hex-5-enyl or exo-hept-6-enyl type radical cyclization when a suitable radical acceptor (e.g. alpha,beta-unsaturated ester. oxime ether or hydrazone) is appropriately placed. Carbohydrate-derived imidazolyl and triazolyl thioates with such acceptors. upon addition to excess of a good hydride donor (reverse addition), undergo moderately efficient cyclization reactions to give N-heterocyclic furanosides, and, surprisingly even N-pyranosides. Depending on the acceptor, glycosides with either C-2-carbon or C-2-amino substituents are formed. In the exo-hept-6-enyl cyclizations the (Z)-olefin acceptors give excellent stereoselectivity in the generation of the C-2 stereogenic center: only altro-isomers are formed. In all cases both alpha- and beta-glycosides are obtained with a moderate preference for the latter. (C) 2003 Elsevier Ltd. All rights reserved.
