A selective one-pot procedure was developed for the production of E-dihalo-substituted α,β-unsaturated alkenoic acids and derivatives from the corresponding α,β-unsaturated alkynoic acids.
Carboxylate-Directed Tandem Functionalisations of α,β-Dihaloalkenoic Acids with 1-Alkynes: A Straightforward Access to (Z)-Configured, α,β-Substituted γ-Alkylidenebutenolides
and stereoselectively leads to rarely described (Z)‐3‐halo‐5‐ylidene‐5H‐furan‐2‐ones. These compounds are subsequently able to undergo classical Pd‐catalysed cross‐coupling reactions, providing 3‐substituted and 3,4‐disubstituted 5‐ylidene‐5H‐furan‐2‐ones (see scheme).
In this study, we screen three heterocyclic structures as potential inhibitors of UDP-galactopyranose mutase (UGM), an enzyme involved in the biosynthesis of the cell wall of Mycobacterium tuberculosis. In order to understand the binding mode, docking simulations are performed on the best inhibitors. Their activity on Mycobacterium tuberculosis is also evaluated. This study made it possible to highlight an "oxazepino-indole" structure as a new inhibitor of UGM and of M. tuberculosis growth in vitro.
