One-pot synthesis of quinazoline derivatives via [2+2+2] cascade annulation of diaryliodonium salts and two nitriles.

An efficient one-pot approach to multiple substituted quinazolines with diaryliodonium salt , and two nitriles has been presented. The reaction enables great flexibility of the substitution patterns on quinazolines and is applicable to two different nitriles to give a regio-selective product.
