【文章名】A facile synthesis of novel heteropolycyclic pyrazines and oxazoles and mechanistic studies of 2,3-dihydrobenzo[de]chromene-7,8-dione with amines.
[摘要]：A series of novel heteropolycyclic pyrazines and oxazoles were synthesized by the reaction of 2,3-dihydrobenzo[de]chromene-7,8-dione with amines under mild reaction conditions. The mechanisms for these reactions were discussed.
