Abstract

Efficient microwave-assisted multi-step synthesis of 8H-quinazolino [4, 3-b] quinazolin-8-one was investigated. The synthesis involved two Niementowski condensations from anthranilic acids. Homogeneous or heterogeneous conditions were studied with the aim to develop convenient syntheses of the desired compounds.
