Abstract

A PEG-mediated green synthesis of 6-pyrazinyl-/fused pyrazinylquinazolin- 4(3H)-ones was developed starting from 6-iodo-3-methyl-2-phenylquinazolin- 4(3H)-one by means of quinazolinone-based internal alkyne/1,2-diketone as intermediates using the Castro?Stephen coupling reaction/potassium permanganate mediated oxidation and cyclocondensation reactions.
