A new type of fused oxazepinones 9a and 9b, which are analogues of sclerotigenin and circumdatinF, were obtained in a two step synthesis from 2-(2-amino-benzoylamino)-benzoic acid or the corresponding methyl ester. Secondly a new synthesis of circumdatinF arose from this work, where 2-(2-propionylamino-benzoylamino)-benzoic acid methyl ester was used as an intermediate.
