metal-free method for the synthesis of quinazolines from 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
在此,报道了一种在乙酸钠存在下由 2-氨基苯基酮和 2,2,2-三氯亚胺酸乙酯盐酸盐合成喹唑啉的无金属方法。本方法具有反应条件温和、原料易得和克级合成等优点。这种方法导致以中等到高产率有效地构建各种喹唑啉衍生物。
