An efficient iridium-catalyzed acceptorless dehydrogenative coupling (ADC) reaction
for the preparation of various quinazolines from 2-aminoarylmethanols and amides or
nitriles had been developed. A wide range of substituted 2-aminobenzyl alcohols and
(hetero)aryl or alkyl benzamides and nitriles were well compatible to afford various
quinazolines in excellent yields. Merits of this new strategy are the high atom-economy,
mild reaction conditions, and simple operation, and the methodology is suitable for
a variety of substrates.
