Paragraph 0032; 0036-0037; 0040, (2020/10/14)
The invention relates to an iron complex containing a diphosphine meta-position carborane ligand as well as a preparation method and application of the same. The iron complex is prepared by the following method: reacting n-BuLi with m-carborane m-C2B10H12, then adding halogenated phosphine for continuous reaction, then adding FeCl2 into a reaction system for continuous reaction, after the reactionis finished, separating the reaction product to obtain an iron complex containing a diphosphine m-carborane ligand, and applying the iron complex to catalytic synthesis of a trans-2-alkenyl azaarenecompound. Compared with the prior art, the method shows efficient catalytic activity in synthesis of the trans-2-alkenyl aza-aromatic hydrocarbon compound through direct condensation reaction of 2-methyl aza-aromatic hydrocarbon and aromatic aldehyde, is low in catalyst dosage, mild in reaction condition, high in reaction rate and relatively high in yield, and has a wide application prospect in industry.

Antibiotic resistance remains a major global public health threat that requires sustained discovery of novel antibacterial agents with unexploited scaffolds. Structure-activity relationship of the first-generation aryl isonitrile compounds we synthesized led to an initial lead molecule that informed the synthesis of a second-generation of aryl isonitriles. From this new series of 20 compounds, three analogues inhibited growth of methicillin-resistant Staphylococcus aureus (MRSA) (from 1 to 4 μM) and were safe to human keratinocytes. Compound 19, with an additional isonitrile group exhibited improved activity against MRSA compared to the first-generation lead compound. This compound emerged as a candidate worthy of further investigation and further reinforced the importance of the isonitrile functionality in the compounds’ anti-MRSA activity. In a murine skin wound model, 19 significantly reduced the burden of MRSA, similar to the antibiotic fusidic acid. In summary, 19 was identified as a new lead aryl isonitrile compound effective against MRSA.
