BM635 is the hit compound of a promising anti-TB compound class. Herein we report systematic variations around the central pyrrole core of BM635 and we describe the design, synthesis, biological evaluation, pharmacokinetic analysis, as well as in vivo TB mouse efficacy studies of novel BM635 analogues that show improved physicochemical properties. This hit-to-lead campaign led to the identification of a new analogue, 4-((1-isopropyl-5-(4-isopropylphenyl)-2-methyl-1H-pyrrol-3-yl)methyl)morpholine (17), that shows excellent activity (MIC = 0.15 μM; SI = 133) against drug-sensitive Mycobacterium tuberculosis strains, as well as efficacy in a murine model of TB infection.
Regioselective cobalt-catalysed hydrovinylation for the synthesis of non-conjugated enones and 1,4-diketones

The highly regioselective cobalt-catalysed 1,4-hydrovinylation of terminal alkenes with 2-trimethylsilyloxy-1,3-butadiene generates in a stereospecific fashion unsaturated E-configured silyl enol ether intermediates that are suitable for diastereoselective Mukaiyama-aldol reactions with bulky aliphatic aldehydes. The acidic hydrolysis of the enol ethers to γ,δ- unsaturated ketones followed by ozonolysis can be used for the synthesis of various 1,4-diketones and polycarbonyl derivatives. The 1,4-diketones and polycarbonyl derivatives were successfully tested for the synthesis of some mono- and bis-pyrrole derivatives. The γ,δ-unsaturated ketones are useful building blocks (e.g., in natural product synthesis) and can be generated in a one-pot procedure. Copyright
Gold(III) complexes catalyze deoximations/transoximations at neutral pH

Golden solution: A neutral solution of AuBr3, containing [AuBr2(OH)2]- in equilibrium with [AuBr 3(OH)]- and [AuBr4]-, promotes the chemoselective hydrolysis of robust oximes into carbonyl compounds without racemization (see scheme). The food additive diacetyl acts as a NH 2OH-trapping agent, thus avoiding the formation of gold nanoparticles and allows the reaction to run catalytically. Copyright
