Exploration on structure and anticonvulsant activity of transition metal complexes derived from an “end-off” compartmental bis-quinoxaline derivative with phthalazinyl-diazine as endogenous bridge

An oligoquinoxaline derivative with phthalazine core has been prepared by condensation of 1,4-dihydrazinophthalazine with 2,3-dichloroquinoxaline in dry ethanol followed by acid hydrolysis. Classical endogenous bridging of phthalazine core with its diazine fragment was established in the transition metal(II) complexes derived from the ligand system by using various physicochemical and spectral techniques. The organic host acts as a hexadentate chelate with N4O2 donating sites for coordination towards later first-row transition metal ions. Complexes are in good agreement with the octahedral geometry and found to be 1:1 electrolytes. All synthesized compounds were screened for anticonvulsant activity in Wistar rats by using maximal electroshock method. The ligand, and Co(II) and Ni(II) complexes show appreciable suppression towards electroshock-induced seizures.

Rapid Construction of Structurally Diverse Quinolizidines, Indolizidines, and Their Analogues via Ruthenium-Catalyzed Asymmetric Cascade Hydrogenation/Reductive Amination

A rapid construction of enantioenriched benzo-fused quinolizidines, indolizidines, and their analogues by ruthenium-catalyzed asymmetric cascade hydrogenation/reductive amination of quinolinyl- and quinoxalinyl-containing ketones has been developed. This reaction proceeds under mild reaction conditions, affording chiral benzo-fused aliphatic N-heterocyclic compounds with structural diversity in good yields (up to 95 %) with excellent diastereoselectivity (up to >20:1 dr) and enantioselectivity (up to >99 % ee). Furthermore, this catalytic protocol is applicable to the formal synthesis of (+)-gephyrotoxin.

Direct oxidative dearomatization of indoles: Access to structurally diverse 2,2-disubstituted indolin-3-ones

Described is an efficient oxidative dearomatization of indoles with TEMPO oxoammonium salt and a broad range of nucleophiles. Under very mild conditions, dearomative oxyalkynylation and oxyalkenylation of indoles to structurally diverse 2,2-disubstituted indolin-3-ones were developed for the first time with high atom-economy. In addition, dearomative oxyarylation, oxyallylation, and oxycyanation of indoles were also demonstrated. Mechanism studies indicated that TEMPO oxoammonium salt served as the sole oxidant source through an electron donor-acceptor (EDA) intermediate.

Mild and highly selective palladium-catalyzed monoarylation of ammonia enabled by the use of bulky biarylphosphine ligands and palladacycle precatalysts

A method for the Pd-catalyzed arylation of ammonia with a wide range of aryl and heteroaryl halides, including challenging five-membered heterocyclic substrates, is described. Excellent selectivity for monoarylation of ammonia to primary arylamines was achieved under mild conditions or at rt by the use of bulky biarylphosphine ligands (L6, L7, and L4) as well as their corresponding aminobiphenyl palladacycle precatalysts (3a, 3b, and 3c). As this process requires neither the use of a glovebox nor high pressures of ammonia, it should be widely applicable.
