- Nickel Hydride Catalyzed Cleavage of Allyl Ethers Induced by Isomerization
-
This report discloses the deallylation of O - and N -allyl functional groups by using a combination of a Ni-H precatalyst and excess Bronsted acid. Key steps are the isomerization of the O - or N -allyl group through Ni-catalyzed double-bond migration followed by Bronsted acid induced O/N-C bond hydrolysis. A variety of functional groups are tolerated in this protocol, highlighting its synthetic value.

- Development of isoniazid-NAD truncated adducts embedding a lipophilic fragment as potential bi-substrate InhA inhibitors and antimycobacterial agents
-
Isoniazid-NAD truncated adducts embedding a lipophilic fragment were designed, synthesized and evaluated as inhibitors of the enoyl-acyl carrier protein (ACP) reductase (InhA) of Mycobacterium tuberculosis and as antimycobacterial agents. These compounds, planned as bi-substrate inhibitors and inspired from the active metabolite of isoniazid, combine both the nicotinamide moiety of the cofactor NAD and a lipophilic hydrocarbon chain mimic of the InhA substrate. The lipophilic fragment was introduced using either Suzuki-Miyaura cross-coupling or a classical nucleophilic substitution reaction. Several compounds developed in this work were indeed able to inhibit the InhA activity and showed promising antimycobacterial activities. However a direct correlation between the expressed activity and the bi-substrate mode of action could not yet be unambiguously demonstrated.

- Thermodynamic, spectroscopic, and density functional theory studies of allyl aryl and prop-1-enyl aryl ethers. Part 1. Thermodynamic data of isomerization
-
A chemical equilibration study of the relative thermodynamic stabilities of seventy isomeric allyl aryl ethers (a) and (Z)-prop-1-enyl aryl ethers (b) in DMSO solution has been carried out. From the variation of the equilibrium constant with temperature the Gibbs energies, enthalpies, and entropies of isomerization at 298.15 K have been evaluated. Because of their low enthalpies, the (Z)-prop-1-enyl aryl ethers are strongly favored at equilibrium, the Gibbs energies of the a→b isomerization ranging from -12 to -23 kJ mol-1. The entropy contribution is negligible in most reactions, but occasionally small positive values less than +10 J K-1 mol-1 of the entropy of isomerization are found. The equilibration studies were also extended to involve two pairs of related isomeric ethers with a Me substituent on C(2) of the olefinic bond. The Me substituent was found to increase the relative thermodynamic stability of the allylic ethers by ca. 3.4 kJ mol-1.
