The cyclization of substituted N‐methoxy benzamides with alkynes in the presence of an easily affordable cobalt complex and NaOAc provides isoquinolone derivatives in good to excellent yields. The cyclization reaction is compatible with a range of functional group‐substituted benzamides, as well as ester‐ and alcohol‐substituted alkynes. The cobalt complex [CoIIICp*(OR)2] (R=Me or Ac) serves as an
在容易负担得起的钴络合物和NaOAc的存在下,用炔烃将取代的N-甲氧基苯甲酰胺环化,可以提供高至优异收率的异喹诺酮衍生物。环化反应与各种官能团取代的苯甲酰胺以及酯和醇取代的炔烃兼容。钴配合物[Co III Cp *(OR)2 ](R = Me或Ac)可作为有效的环化反应催化剂。后来,在POCl 3或PBr 3的存在下,异喹诺酮衍生物以极高的收率转化为1-氯和1-溴取代的异喹啉衍生物。
