An improved and simpler method for the synthesis of benzodiazepin-2,5-diones and 7-iodobenzodiazepin-2,5-diones catalyzed by glacial acetic acid using isatoic anhydride and 6-iodoisatoic anhydride, respectively, as starting materials is reported. The target products were achieved in good yields (up to 71percent) using microwave irradiation as the activating mode of reaction in the presence of acetic acid instead of the traditional polar aprotic solvents as dimethylformamide (DMF), dimethyl sulfoxide (DMSO) or dimethylacetamide (DMAC). Moreover, relatively simple purification workup is required. The optimal temperature to obtain the benzodiazepin-2,5-dione derivatives was 130 °C, while the best irradiation time was 3 min. In addition, the methodology for the selective preparation of 6-iodoisatoic anhydride with an overall yield of 62percent is presented. Printed in Brazil-

A family of 1,4-benzodiazepine-2,5-diones and quinazolinones with diverse substituents at the C-3 position were synthesized via a novel, simple and convenient methodology using H2PtCl6 as the catalyst. The substitution at the C-3 pos

The continual increase in drug resistance; the lack of new chemotherapeutic agents; the toxicity of existing agents and the increasing morbidity with HIV co-infection mean the search for new antileishmanial agents has never been more urgent. We have ident
