An efficient synthesis of 2,3-dihydroquinazolin-4(1H)-ones proceeding via a three-component reaction between benzyl alcohols, isatoic anhydride, and primary amines in the presence of iodine and potassium carbonate is reported. This protocol allows the straightforward preparation of the titled products using readily available benzyl alcohols instead of unstable aldehydes under mild oxidative conditions
据报道,在碘和碳酸钾的存在下,通过苄醇,isatoic酸酐和伯胺之间的三组分反应,可以有效地合成2,3-二氢喹唑啉-4(1 H)-ones。该方案允许在温和的氧化条件下使用容易获得的苄醇代替不稳定的醛直接制备标题产品。
