simple and efficient synthesis of 11H-pyrido[2,1-b]quinazolin-11-ones by Cu(OAc)2·H2O-catalyzed reaction of easily available substituted isatins and 2-bromopyridine derivatives has been developed. The reaction involves C–N/C–C bond cleavage and two C–N bond formations in a one-pot operation. This methodology is complementary to previously reported synthetic procedures, and two plausible reaction mechanisms
通过Cu(OAc)2 ·H 2 O催化易得的取代的靛红与2-溴吡啶衍生物的反应,可以简单,有效地合成11 H-吡啶并[ 2,1 - b ]喹唑啉-11-酮。该反应在一锅操作中涉及C–N / CC键断裂和两个C–N键形成。该方法是对先前报道的合成方法的补充,并讨论了两个合理的反应机理。
