Abstract
This study focuses on the synthesis of 1,7- and 3,4-indole-fused lactones via a simple and efficient reaction sequence. The functionalization of these "oxazepino-indole" and "oxepino-indole" tricycles is carried out by palladium catalysed CC coupling, nucleophilic substitution or 1,3-dipolar cycloaddition. The evaluation of their activity against Mycobacterium tuberculosis shows that the "oxazepino-indole" structure is a new inhibitor of M. tuberculosis growth in vitro.
