摘要

Pyrrolo [2, 1-c][1, 4] benzodiazepines (PBDs) and the corresponding pyrrolobenzothiadiazepines (PBTDs) are attractive targets as natural and synthetic antitumour antibiotics and as non-nucleosidic reverse transcriptase inhibitors. A concise synthesis of the PBTD class is presented, which starts from o-azidobenzenesulfonamide and its conversion into 2-(o-azidobenzenesulfonyl)-1, 2-thiazine 1-oxides via Diels–Alder ...
