Reaction of imidoformates with anthranilates: Facile, one-pot, three-component synthesis of 8H-quinazolino[4,3-b]quinazolin-8-ones

摘要

We report a facile, one-pot, three-component methodology for the synthesis of 8H-quinazolino[4,3-b]quinazolin-8-ones from commercially available 2-aminobenzonitriles, triethyl orthoformate, and anthranilic acids/esters/amides in good yields.
