A catalytic desymmetrization of strained alkenes by ring-opening of meso-diazabicycles with acyl anion nucleophiles is reported. Densely functionalized frans-1,2-hydrazinoacyl cyclopentene building blocks are obtained stereoselectively. The acyl anion equ

A series of 15 heteroarotinoids has been prepared and evaluated for activity against Mycobacterium bovis BCG with the thiourea-containing isoxyl (7) (0.5 μg/mL) as the standard. 2,2,4-Trimethyl-2H-chromen-7-yl 4-(methoxycarbonyl)benzoate (8) displayed the most significant activity (2.0-4. 0 μg/mL) in terms of the lowest concentration (μg/mL) (MIC, minimum inhibitory concentration) required to produce a 99% reduction in the number of colonies on a plate as compared to that system free of the agent at the same dilution of the culture suspension. Ethyl 4-{[N-(2,2,4,4-tetramethylchroman-6-yl)thiocarbamoyl]amino}benzoate (9) and [(1E,3Z,5E)-1-aza-4-methyl-6-(1,2,2,4-tetramethyl(1,2-dihydroquinolyl))hexa-1,3, 5-trienyl]amino}aminomethane-1-thione (10) exhibited activity at 5.0-10.0 and 10.0-20.0 μg/mL, respectively, while the other examples had MIC values of 20 μg/mL or greater. The inhibitory ability of 8 may occur via the inhibition of mycolic acid synthesis in a like manner as found with 7, but this requires further study. The heteroarotinoids are the first examples to exhibit inhibitory ability against the growth of Mycobacterium bovis BCB.
