  An allylation-metathesis sequence as a convergent strategy towards enantiopure equivalents of highly functionalized cyclic dienes

  摘要：

  Highly enantioenriched equivalents of cyclic dienes have been readily prepared by asymmetric allylation of unsaturated aldehydes using a chiral allyltitanium reagent, followed by a ring-closing metathesis. The resulting beta-hydroxy allylsilanes react stereoselectively with a wide variety of electrophilic reagents. (C) 2003 Elsevier Ltd. All rights reserved.
