[PMID: 38407036 PMCID: PMC10949238 DOI: 10.1021/acs.joc.3c02859] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2023] [Revised: 01/30/2024] [Accepted: 02/06/2024] [Indexed: 02/27/2024]
Abstract
Herein, we report the catalytic allylic amination of α-methylalkenes with V2O3Dipic2(HMPA)2 and chloramine T as the quantitative source of N. The reaction works with high yields and stereoselectivities for α-methylalkenes. A proposed tosylnitrene-free catalytic cycle involving the formation of vanadoxaziridine complex 1 as the active catalyst and aminovanadation across the substrate as the rate-determining step has been proposed. Initial kinetic and competition experiments provide evidence for the proposed mechanism.

Abstract
Herein we report the WO2Dipic(H2O) promoted oxyamination of alkenes using sulfonamides as the quantitative source of N. The reaction works for activated and unactivated alkenes in high yields, diastereoselectivities, and stereospecificity. A catalytic cycle involving the formation of tungstenooxaziridine complex 1 as the active catalyst and hydrolysis of tungstenooxazolidine intermediate A as the rate-determining-step has been proposed. Initial kinetic and competition experiments provide evidence for the proposed mechanism.

Abstract
Osmium(IV) pyrazole compounds and ligands were synthesized and well characterised. Ligands were characterized by heteronuclear NMR spectroscopy (1H & 13C), elemental analysis, IR spectroscopy and liquid crystal mass spectroscopy. Os(IV) complexes were characterized by ESI-MS, ICP-OES, IR spectroscopy, conductance measurements, magnetic measurements and electronic spectroscopy. Binding of compounds with HS-DNA were evaluated using viscosity measurements, absorption titration, fluorescence quenching, and molecular docking, which show effective intercalation mode exhibited by compounds. Binding constant of Os(IV) complexes are found to be 8.1 to 9.2 × 104 M-1. Bacteriostatic and cytotoxic activities were carried out to evaluate MIC, LC50, and IC50. The compounds have been undergone bacteriostatic screening using three sets of Gram+ve and two sets of Gram-ve bacteria. MIC of complexes are found to be 72.5-100 μM, whereas that of ligands fall at about 122.5-150 μM.. LC50 count of ligands fall in the range of 16.22-17.28 μg/mL whereas that of complexes of Os(IV) fall in the range of 4.87-5.87 μg/mL. IC50 of osmium compounds were evaluated using HCT-116 cell line. All the Os(IV) compounds show moderate IC50.
