Venkateswarlu, Somepalli; Satyanarayana, Meka; Murthy, Gandrothu Narasimha; Siddaiah, Vidavalur published the artcile< Cyclisation of 2-(2-aminophenyl)quinazolin-4(3H)-one reexamined: formation of isomeric angular fused quinazolinoquinazolinones and their spectroscopic identification>, Reference of 5004-88-6, the main research area is aminophenylquinazolinone acetic anhydride cyclization; isomeric angular fused quinazolinoquinazolinone preparation IR NMR.
Cyclization of 2-(2-aminophenyl)quinazolin-4(3H)-ones on N3 and on N1 leading to 6-alkyl-(8H)-quinazolino[4,3-b]quinazolin-8-ones and 6-alkyl-(13H)-quinazolino[3,4-a]quinazolin-13-ones, resp. was described for the first time. The differences in the IR and carbon NMR data of these isomeric fused quinazolinoquinazolinones afford a useful method for distinguishing between the two series.
