  Stereocontrolled entry to β-C-glycosides and bis-C,C-glycosides from C-glycals: preparation of a highly functionalized triene from d-mannose

  摘要：

  The C(3) hydroxyl group of C-glycals can be readily converted into mixed halo-acetals of 2-bromo-acetaldehyde. Radical reaction of the latter mediated by tri-n-butyltin hydride, with or without a radical acceptor, led diastereoselectively to either beta -C-glycosides or bis-C,C-glycosides, respectively. The latter have been transformed into a highly functionalized triene, which is a potential precursor in a proposed synthesis of labdane type diterpenes from D-mannose. (C) 2001 Elsevier Science Ltd.
