Abstract: Treatment of 1-(2-bromoarylmethyl)-3,4-dihydroisoquinolines with oxalyl chloride and triethylamine gave 1-(2-bromophenyl)-5,6-dihydropyrrolo[2,1-a]isoquinoline-2,3-dione derivatives, for example, 1-(2-bromophenyl)-5,6-dihydro-8,9-dimethoxypyrrolo[2,1-a]isoquinoline-2,3-dione. Radical cyclisation of these derivatives with tributyltin hydride and 1,1-azobis(cyclohexanecarbonitrile) afforded telisatin A, telisatin B and lettowianthine.
