Diverse functionalized quinoxalines were synthesized in good yields from arylamines and readily available β-keto oximes through condensation and metal-free N-arylation. The reaction was compatible with various functional groups, such as halides, cyano, and esters. A mechanism was proposed based on the experimental results. These quinoxalines were easily obtained on a gram scale and converted to various
通过缩合和无金属的N-芳基化反应,由芳基胺和易于获得的β-酮肟以高收率合成了多种功能化的喹喔啉。该反应与各种官能团相容,例如卤化物,氰基和酯。根据实验结果提出了一种机理。这些喹喔啉可以以克为单位轻松获得,并转化为各种有用的支架。分两步以83%的产率制备化合物LASSBio-1022。
