| Abstract: | 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. |
