  A practical one-pot radical-ionic sequence for the preparation of epoxides: application to the synthesis of unnatural polyhydroxylated alkaloids

  摘要：

  An efficient one-pot sequence for the preparation of epoxides from alpha-iodoesters or alpha-iodonitriles and allylic alcohols is described. This sequence is based on the use of iodine atom transfer reaction onto allylic alcohols followed by a ring closing epoxidation reaction of the halohydrin intermediates. The feasibility of this sequence is showcased in the synthesis of the perhydroaza-azulene, an unnatural analog of castanospermine. (C) 2011 Elsevier Ltd. All rights reserved.
