  名称：

  A facile entry into a novel class of dispiroheterocyclic framework through 1,3-dipolarcycloaddition of azomethine ylides with 3-arylidene-4-chromanones as dipolarophiles

  摘要：

  The cycloaddition reaction of azomethine ylides, generated through decarboxylation, with (E)-3-arylidene-4-chromanones as dipolarophiles has been investigated. A high degree of regioselectivity has been observed in the synthesis of a new class of functionalized dispiroheterocyclic compounds bearing chromanone and acenaphthenequinone framework. The structures were established by spectroscopic techniques as well as single crystal X-ray analysis. (C) 2009 Elsevier Ltd. All rights reserved.
