  Convenient strategy for the synthesis of highly functionalizable hydroxylated unsaturated azepanes

  摘要：

  A convenient approach to the construction of dihydroxylated unsaturated azepanes featuring a functional group (ethoxycarbonyl)methyl or (cyano)methyl at C-2 was achieved from a pent-4-enal synthon obtained in four steps from D-xylose. The key step of the sequence relied on the conjugate addition of allylamine to alpha,beta-unsaturated ester or nitrile, prepared by Wadsworth-Emmons olefination. Subsequent RCM afforded the target unsaturated azepanes. (C) 2012 Elsevier Ltd. All rights reserved.
