A series of synthetically interesting 2-arylbenzoxazinones was prepared from 2-arylindoles by an efficient oxidative reaction mediated by (diacetoxyiodo)benzene [PhI(OAc) 2 ] and assisted by water. PhI(OAc) 2 was used as the sole oxi

A practical synthesis of 2,3-disubstituted 3H-quinazolin-4-ones 1 with broad chemistry scope is described. The key step is the microwave promoted one-pot, two-step reaction sequence combining anthranilic acids, carboxylic acids, and amines providing efficient access to this important class of heterocycles.
1H and 13C NMR spectral studies of some 4H-3,1-benzoxazin-4-ones and their 2-acylaminobenzoic acid precursors

The 1H and 13C NMR spectra of twelve 4H-3,1-benzoxazine-4-ones and of their acylaminobenzoic acid precursors are presented. Differentiation between these two series of compounds is best achieved through the characteristic JCH coupling interactions in the high frequency carbonyl region. Some 4H-pyrido[2,3-d][1,3]oxazin-4-ones have also been studied and some earlier literature assignments revised.
