Abstract :
The cycloaddition reaction of non-stabilized azomethine ylides towards (E)-3-arylidene-4-flavanone, (E)-3- arylidene-4-chromanone and (E)-2-arylidene-1-tetralone as dipolarophiles has been investigated. High degree of regioselectivity has been observed in the synthesis of a new class of functionalised dispiroheterocyclic compound containing dispiro pyrrolo-isoquinoline and acenaphthequinone framework.
