metal-free method for the synthesis of quinazolinesfrom 2-aminophenyl ketones and 2,2,2‑trichloroethyl imidates hydrochloride in the presence of sodium acetate is reported. The present approach has advantages including mild reaction conditions, readily available starting materials, and gram-scale synthesis. This methodology leads to an efficient construction of various quinazoline derivatives in moderate
2,2,2-Trifluoro- and trichloroethyl imidates, which are easily prepared by reaction of a nitrile and a trihaloethanol in the presence of HCl, have proven to be excellent reagents for the preparation of amidines under mild reaction conditions. Depending on the nature of the amine nucleophile, the imidates can react either as the free-base or the hydrochloride salt in a telescoped process. In several
