The synthesis of the antimigraine drug 1-[bis(4-fluorophenyl)methyl]-4-(2, 3,4-trimethoxybenzyl)piperazine has been carried out in very good yields. The five-step synthesis started from bis(4-fluorophenyl)methanone. This route can be applied for large-scale preparation of lomerizine. Georg Thieme Verlag Stuttgart.

Herein, we describe the successful design and synthesis of seventeen new 1,4-diazinanes, compounds commonly known as piperazines. This group of piperazine derivatives (3a-q) were fully characterized by 1H NMR, 13C NMR, FT-IR, and LCMS spectral techniques. The molecular structure of piperazine derivative (3h) was further established by single crystal X-ray diffraction analysis. All reported compounds were evaluated for their antibacterial and antifungal potential against five bacterial (Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Acinetobacter baumannii, and Pseudomonas aeruginosa) and two fungal strains (Candida albicans and Cryptococcus neoformans). The complete bacterial screening results are provided. As documented, piperazine derivative 3e performed the best against these bacteria. Additionally, data obtained during molecular docking studies are very encouraging with respect to potential utilization of these compounds to help overcome microbe resistance to pharmaceutical drugs, as explicitly noted in this manuscript.

The borylation of C?H bonds catalyzed by transition metals has been investigated extensively in the past two decades, but no iridium-catalyzed enantioselective borylation of C?H bonds has been reported. We report a set of iridium-catalyzed enantioselective borylations of aromatic C?H bonds. This reaction relies on a set of newly developed chiral quinolyl oxazoline ligands. This process proceeds under mild conditions with good to excellent enantioselectivity, and the borylated products can be converted to enantioenriched derivatives containing new C?O, C?C, C?Cl, or C?Br bonds.
