Synthesis of novel tricyclic pyrimido[4,5-6][1,4]benzothiazepines via Bischler-Napieralski-type reactions

Fu, Renzhong,Xu, Xianxiu,Dang, Qun,Bai, Xu

, p. 10810 - 10816 (2005)

Novel tricyclic pyrimido[4,5-6][1,4]benzothiazepines were readily prepared from 5-amino-4,6-bis-(arylthio)pyrimidines and carboxylic acids via Bischler-Napieralski-type reactions. The 6-aryl sulfide group of the resulting pyrimido[4,5-6][1,4]benzothiazepi
