Synthesis of a new hetrocyclic system 7,8-dihydroimidazo[1,2-c][1,3]oxazolo[4,5-e]pyrimidine
摘要:
2-(Acylaminocyanomethylene)imidazolidines are formed on interacting 2-acylamino-3,3-dichloro-acrylonitriles with ethylenediamine. The former are converted into new derivatives of oxazolo[ 4,5-e] pyrimidine on treatment with trifluoroacetic acid, and then with triethyl orthoformate.
