The glycolytic pathway has been considered a potential drug target against the parasitic protozoan species of Trypanosoma and Leishmania. We report the design and the synthesis of inhibitors targeted against Trypanosoma brucei phosphofructokinase (PFK) and Leishmania mexicana pyruvate kinase (PyK). Stepwise library synthesis and inhibitor design from a rational starting point identified furanose sugar amino amides as a novel class of inhibitors for both enzymes with IC50 values of 23 muM and 26 muM against PFK and PyK, respectively. Trypanocidal activity also showed potency in the low micromolar range and confirms these inhibitors as promising candidates for the development towards the design of anti-trypanosomal drugs.

Treatment of the alpha-dimethylamino[3]ferrocenophane system 3 with methyl iodide followed by dimesitylphosphine (Mes2PH) gave the alpha-(dimesitylphosphino)[3]ferrocenophane 5. This forms a frustrated Lewis pair [5/8] with B(C6F5)3 (8) that rapidly reacts with dihydrogen under ambient conditions to probably give the phosphonium cation/hydrido borate anion salt [5-H+/H-8-]. This, however, is unstable under the applied reaction conditions with regard to replacement of the newly formed phosphonium leaving group at the ferrocenophane a-position for hydride from the [HB(C6F5)3 -] counteranion to eventually yield the unfunctionalized [3]ferrocenophane product (10) and Mes2PH· B(C 6F5)3 (11) – both characterized by independent syntheses. Analogously, Ugi’s amine (6) was converted to (1-(dimesitylphosphino) -ethyl)ferrocene (7). The frustrated pair [7/8] consumes dihydrogen under similar conditions to yield the reduction products ethylferrocene (14) and Mes2PH · B(C6F5)3 (11).

A H2O-regulated chemoselective addition in oxa- and aza-Michael reactions for aminoalcohols and mixtures of structurally similar alcohols and amines was reported. The oxa-Michael reactions might be kinetically controlled, and the reactions to produce O-selective products were slowed by the addition of water. The electrophilicity of Michael acceptors and the steric hindrance of Michael donors also affect the ratios of O/N products. This method offers novel ideas over conventional metal-catalyzed or ligand-induced strategies.

Herein, we report the first example of the asymmetric hydrogenation of a prochiral benzodiazepine substrate as key transformation in a pilot-scale synthesis of BET inhibitor BAY 1238097. High-throughput screening in a parallel reactor enabled us to identify an efficient catalyst based on Ir and a chiral bisphosphine. An additive screening allowed significant reduction of catalyst loading. Ultimately, the hydrogenation was performed on a kilogram scale leading to the production of 27 kg of the desired product with an enantiomeric excess of 99% after crystallization.
