Enzymatic resolution and dynamickineticresolution of γ-hydroxy acid derivatives 1 have been investigated. Efficient kineticresolution was obtained using Pseudomonas cepacia lipase in toluene (E value ∼400). The combination of enzymatic kineticresolution with a ruthenium-catalyzed racemization resulted in an efficient dynamickineticresolution. The use of a hydrogen source to depress ketone formation

The invention relates to bi-substrate inhibitor molecules associating (i) a pyridine, pyridinium or dihydropyridine-type structure allied to active metabolites of isoniazide, or related structures, and (ii) a hydrophobic substituent. The invention also relates to the method for producing said molecules, to the pharmaceutical compositions containing said molecules, and to the use thereof as inhibitors of enoyl reductase for the preparation of a medicament, especially an anti-infectious medicament for the treatment of tuberculosis.

efficient kineticresolution of racemic γ-hydroxy amides 1 was performed via Pseudomas cepacia lipase (PS-C)-catalyzed transesterification. The enzyme PS-C tolerates both variation in the chain length and different functionalities giving good to high enantioselectivity (E values of up to >250). The combination of enzymatic kineticresolution with a ruthenium-catalyzed racemization led to a dynamic kinetic
