[摘要]：Naphthoquinones undergo 1,3-dipolar cycloaddition with bicyclic munchnones generated from thiazolidines affording new pyrrolo-thiazoles with a fused quinone nucleus. The products were obtained as single enantiomers in good yields. These benzo[f]thiazolo[4,3-a]isoindole-6,11(1H,3H)-diones are comprised of four fused rings and present a very planar structure. The evaluation of their anticancer activity against melanoma A375 and colorectal adenocarcinoma WiDr human cell lines showed only moderate activity but gave insight into the modeling of new structures.
