1,3-Azoles from ortho-naphthoquinones: Synthesis of aryl substituted imidazoles and oxazoles and their potent activity against Mycobacterium tuberculosis
摘要:
Twenty-three naphthoimidazoles and six naphthoxazoles were synthesised and evaluated against susceptible and rifampicin- and isoniazid-resistant strains of Mycobacterium tuberculosis. Among all the compounds evaluated, fourteen presented MIC values in the range of 0.78 to 6.25 mu g/mL against susceptible and resistant strains of M. tuberculosis, Five structures were solved by X-ray crystallographic analysis. These substances are promising antimycobacterial prototypes. (C) 2012 Elsevier Ltd. All rights reserved.

The implementation of a π-expansion strategy based on the Ru(II)-catalyzed alkyneannulation reactions of nonsymmetricimidazoles prepared from β-lapachone and nor-β-lapachone is reported. Photophysical aspects and the mechanism of the computationally studied reaction were also investigated by us and are described and discussed in detail.
