Novel benzothiazole derivatives have been synthesised via the corresponding imino-1,2,3-dithiazoles. The cytotoxicity of some of these polyheterocyclic compounds was studied. Our results show that 2-cyano derivatives exhibit a medium in vitro antitumour activity. (C) 1999 Editions scientifiques et medicales Elsevier SAS.

The synthesis of new dioxinobenzothiazoles is described. Introduction of the thiazole moiety of these new polyheterocyclic systems was realised by the use of imino-1,2,3-dithiazoles. Several steps in these multistep synthesis were transposed to a focused microwave oven. (C) 1999 Elsevier Science Ltd. All rights reserved.

Novel 3,1-benzoxazinones, 3,1-benzothiazinones and 4-alkoxyquinazolines have been synthesized via N-aryl-1,2,3-dithiazoles derivatives. The antibacterial and antifungal activity of these compounds were measured; the dithiazoles are significantly active against fungi. Copyright (C) 1996 Elsevier Science Ltd
