Description
Summary:Optimal conditions were developed for the synthesis of 11 H -isoindolo[2,1- a ]benzimidazol-11-one, 5 H -isoindolo[2,1- a ][3,1]benzoxazine-5,11(6a H )-dione, and 6,6a-dihydroisoindolo[2,1- a ]quinazoline-5,11-dione derivatives in the reaction of substituted 2-formylbenzoic acids with o-phenylenediamine, anthranilic acid, and anthranilamide, respectively. The bifolded structure of 6,6a-dihydroisoindolo-[1,2- a ]quinazoline-5,11-dione was verified and investigated.
