  Synthesis of highly substituted 2,6-anti-configured tetrahydropyrans. First steps towards an efficient access to amphidinol 3 ring system

  摘要：

  Highly functionalised and polysubstituted tetrahydropyrans, akin to the middle core of the amphidinols, can be efficiently synthesised, with full stereocontrol and in good yields, using as key steps an anti-allylation reaction coupled with an intramolecular Sakurai cyclisation. Three approaches were devised in order to reach a broad range of substitution patterns. (c) 2005 Elsevier Ltd. All rights reserved.

  Stereoselective synthesis of functionalised triol units by SnCl4 promoted allylation of α-benzyloxyaldehydes: crucial role of the stoichiometry of the Lewis acid

  摘要：

  Enantiomerically pure syn-anti and syn-syn configured triol units are efficiently synthesized by the SnCl4 mediated allylation of chiral alpha-benzyloxyaldehydes with the uniquely functionalised allylstannane 9. Remarkably, the stereochemistry of the adducts is solely governed by the amount of Lewis acid employed. (C) 2004 Elsevier Ltd. All rights reserved.

  日期：2002.1.1

  [GRAPHICS]The condensation between a functionalized allylstannane and alpha-alkoxyaldehydes allows rapid access to complex and selectively protected trihydroxylated synthons. The stereocontrol of this process is strongly dependent upon the nature and the amount of the Lewis acid employed.
