hydrogenation protocol is free from the requirement for adding any auxiliary reagent to elicit the catalytic activity of the applied metal complex. Moreover, a containment system is not required for the assembly of the hydrogenation reaction set‐up as both the autoclave and the reaction vessels are readily charged under a regular laboratory atmosphere.
A vasoactive drug is provided which comprises a compound having GPR14-antagonizing activity or salts thereof.

catalytic arylhydroxylation of dehydroalanine with aryldiazonium salts. Aryldiazonium salts, which are generated from aniline precursors under partially aqueous conditions in continuous flow, efficiently reacted with dehydroalanine in the presence of 10–15 mol % ferrocene to furnish α‐hydroxyarylalanine derivatives (up to 82 % yield). The reactions proceeded with regioselectivity, broad functional
derivatives as small-molecule Omicron fusion inhibitors with improvedpotency and selectivity index. Particularly, our medicinal chemistry efforts have resulted in a potent, and efficacious lead compound S-10 with appreciable pharmacokinetic properties, which exhibited broad-spectrum potency against Omicron and other variants with EC50 values ranging from 0.82 to 5.45 μM. Mutagenesis studies confirmed that

Amine or diphosphine complexed Mn(II) compounds reversibly adsorb sulfur dioxide and oxygen as well as nitrogen oxides, carbon monoxide, carbon dioxide and lower alkenes. More specifically, these compounds have the following formula:
Mn(II)LX₂
where X represents F⁻, Br⁻, Cl⁻, I⁻, SCN⁻ or OH⁻. L is a ligand having the formula N(R₁)n; R₂-N = N - R₃ or
The metal complexes are used to adsorb gases as a solid adsorbent, suspended on aluminum oxide or dissolved in a non-volatile solvent. The gas can be adsorbed at a low temperature in the range of 30-200°C, and desorbed at a higher temperature in the range of 45-230°C or at a lower pressure.
