A one-pot three-component tandem reaction involving a key Pictet-Spengler-like annulation step has been developed, providing an efficient method for the synthesis of 3,4-dihydroquinazolines in moderate to good yields from amides, aldehydes, and amines. The multicomponent triflic anhydride mediated reaction tolerates the installation of numerous functional groups, affording extensive diversity about
已经开发了涉及关键的Pictet-Spengler样环化步骤的一锅三组分串联反应,为从酰胺,醛和胺中到高收率的合成3,4-二氢喹唑啉提供了一种有效的方法。多组分三氟甲磺酸酐介导的反应可耐受许多官能团的安装,从而为杂环支架提供了广泛的多样性。
