摘要：

A silver-catalyzed [5+1] annulation of o-acylaryl isocyanides with ammonium acetate and hydroxlamine was developed for the efficient and practical synthesis of quinazolines and quinazoline 3-oxides in good to excellent yields, respectively. The domino process involved an unprecedented isocyanide insertion into the N-H bond of ammonia or hydroxylamine and followed by condensation reaction at ambient conditions.
