A regioselective and highly efficient synthesis of 6-amino-substituted pyridin-2(1H)-ones is presented. In situ generated propiolic acid chloride was used for the cyclization of acyclic β-keto N,S-acetals to afford the heterocyclic core. Substitution by amines led to a flexible access of the target compounds.
本文介绍了一种 6-氨基取代的吡啶-2(1H)-酮的区域选择性高效合成方法。原位生成的氯化丙炔酸被用于无环δ-酮 N,S-乙醛的环化,从而得到杂环核心。通过胺的取代,可以灵活地获得目标化合物。
