Abstract
A simple and efficient route for the synthesis of a series of new mono/bis isoxazolines, and pyrroline linked chromone heterocyclic hybrids has been developed from 2-aminochromone via key intermediate mono and 2-(diallylamino)chromen-4-one. The intermediate subjected to the [1,3] dipolar cycloaddition with insitu generated nitrile oxides and ring-closing metathesis to generate the regio selective Isoxazolines and 3-pyrrolines. All the derivatives were screened for their anti-cancer activity (Cell viability), compared to the standard drug Imatinib. Compounds 13b and 13e, 14b and 14g showed good inhibition at 10 µM concentration.
