Development of efficient synthetic methods of nitrogen containing heterocycles by one-pot sequential reactions

We studied for the development of efficient synthetic methods of nitrogen containing heterocyclesand obtained the following results1) efficient synthetic方法for amide substituted imidazolines and benzimidazoles at2-posittion was developed. 2) the novel synthetic method for oxazoles was developed. 3) a tandem反应提供(N-indolyl)- keto esters and o-alkynyl anilines -keto esters and o-alkynyl anilines unsaturated esters fromwas developed。
