8H-Pyrazolo[5',1':2,3]pyrimido[5,4-d][1,2]diazepine: A New Tricyclic System
摘要:
Starting from a series of 6-acetyl-7-(2-dimethylaminovinyl)pyrazolo[1,5-a]pyrimidines (2a-g), several derivatives of the pyrazolo[5',1':2,3]pyrimido[5,4-d][1,2]diazepine system (3a-g) were obtained by reaction with hydrazine hydrate. Some compounds were finally alkylated at N -8 position.
