  Structural and Stereochemical Diversity from (±)-2,2-Dimethyl-8-oxabicyclo[3.2.1]oct-6-en-3-one − Application to the Synthesis of Polyketide Segments of Natural Products

  摘要：

  The racemic title compound has been transformed into both Cyclic and acyclic segments of bioactive natural products, including the C10-C17 segment of pederin, the C12-C19 (C12'-C19') segment of disorazole and the C1-C9 segment of auriside. A methodology for the opening of six-membered ring acetals, containing gem-dimethyl groups, to 5-hydroxyl,3-dithianes has been developed.((C) Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2002).
