to this ring system has been reported yet. Herein, a facileone-pot synthesis from N-aryl itaconimides and 1,3-diarylisobenzofuran via strong acid triggered skeletal rearrangement reaction is described. Theoreticalstudy for this rearrangement is provided at M11/cc-pVDZ level of theory. Antitumor activity of obtained benzo[h]isoquinoline derivatives against human erythroleukemia K562 cell line was evaluated

Treatment of several Diels–Alder adducts of N-aryl itaconimides and 1,3-diphenylisobenzofuran with a strong acid triggers a skeletal rearrangement resulting in 2-aryl-6,10b-diphenylbenzo[h]isoquinoline-1,3(2H,10bH)-diones.
用强酸处理N-芳基衣康酰亚胺和1,3-二苯基异苯并呋喃的几种Diels-Alder加合物会引起骨骼重排,从而导致2-芳基-6,10b-二苯基苯并[ h ]异喹啉-1,3(2 H,10b H)-二酮。
