Systematic synthesis of phthalimide-protected unsaturated hydrazine heterocycles

A four-step route for the synthesis of novel phthalimide-protected hydrazine heterocycles that include a C?C double bond in the cycle was developed. Phthalimide-protected Boc-hydrazine was used as a starting material, which was alkylated with bromoalkenes in mild conditions. Further steps involved Boc-deprotection and second alkylation with bromoalkenes. Finally, the heterocycles were produced by ring-closing metathesis. This route allows access to these versatile building blocks without using electrophilic amination or nitrosylation, therefore, significantly reducing environmental and safety concerns. Phthalimide-protected heterocycles can be derivatized further by modifying the carbon?carbon double bond and by deprotection and subsequent functionalization of the primary amino group. During the current research, various five- to seven-membered hydrazine heterocycles and numerous novel intermediate compounds were synthesized and thoroughly characterized.

Synthesis and characterization of the transition metal complexes: Their alcohol oxidation and electrochemical properties

Five Schiff base ligands, HA1, HA2, H 2L1-H2L3, and their Co(II), Mn(III) and Ru(III) complexes, have been synthesized and characterized by analytical, spectroscopic, conductance, magnetic moment, and electrochemical studies. The oxidation of benzylic alcohols to the corresponding carbonyl compounds is described. In the case of some primary benzyl alcohols, high conversions were obtained. Secondary benzyl alcohol (2-hydroxy-1,2-diphenylethanone derivatives) were selectively transformed to the corresponding ketone with satisfactory conversions. The electrochemical properties of all complexes have been recorded in the different scan rates and solvents. The electrochemical properties of the complexes change with scan rates.

Ruthenium(II) Charge-Transfer Sensitizers Containing 4,4?-Dicarboxy-2,2?-bipyridine. Synthesis, Properties, and Bonding Mode of Coordinated Thio- and Selenocyanates

The synthesis and properties of several complexes of Ru(II) containing 4,4?-dicarboxy-2,2?-bipyridine (dcbpyH2), 2,6-bis(1-methylbenzimidazol-2-yl)pyridine (bmipy), or 2,6-bis(1-methylbenzimidazol-2-yl)-4-phenylpyridine (phbmipy), and monodentate ligands (X- = Cl-, I-, NCS-, NCSe-, CN-) are reported. The introduction of the ambident ligands X- = NCS-, NCSe-, and CN- into the coordination sphere of [Ru(bmipy)(dcbpy)I]- and cis-Ru(dcbpyH2)2Cl2 has been studied in situ via 1H and 13C NMR spectroscopy using 13C-enriched ligands X-. Introduction of thiocyanate and selenocyanate initially yields the two possible linkage isomers in comparable amounts; prolonged reaction time converts the S-bound isomer and the Se-bound isomer to the N-bound isomers. The isoselenocyanate complex decomposes rapidly, yielding the cyano complex under loss of Se. The N-bound isothiocyanato complex K[Ru(bmipy)(dcbpy)(NCS)] was found to be an efficient sensitizer for nanocrystalline TiO2; the incident monochromatic photon-to-current efficiency (IPCE) is nearly quantitative at 520 nm. Introduction of a phenyl group in the 4-position of the 2,6-bis(1-methylbenzimidazol-2-yl)pyridine ligand gives a red-shifted absorption maximum for the corresponding phenylated K[Ru(ph-bmipy)(dcbpy)(NCS)] complex with an increased molar absorption coefficient for the MLCT maximum at 508 nm. At longer wavelengths above 620 nm, phenyl substitution does not enhance the absorption coefficients of the complex. Compared to that of K[Ru(bmipy)(dcbpy)(NCS)], the performance of the phenylated complex is reduced in a solar cell due to lower IPCE values. The visible spectra of the halide complexes K[Ru(bmipy)(dcbpy)X] (X- = Cl-, I-) show enhanced red response, but the complexes exhibit strongly reduced overall IPCE values. A comparison of the complexes to cis-Ru(dcbpyH2)2(NCS)2 is presented. Possible strategies for the design of more efficient sensitizers are discussed.

Synthesis of new mono-N-tosylated diamine ligands based on (R)-(+)-limonene and their application in asymmetric transfer hydrogenation of ketones and imines

A synthetic procedure leading to the preparation of a new family of enantiopure mono-N-tosylated-1,2-diamines derived from (R)-(+)-limonene is described. (+)-Limonene was transformed into the appropriate N-tosyl derivative using N-tosylaziridination based on chloramine-T trihydrate. Subsequent ring opening by sodium azide afforded the corresponding isomeric azides. Finally, reduction of the azide function gave enantiomerically pure mono-N-tosylated-1,2- diamines. The ligands obtained proved to be effective in the asymmetric transfer hydrogenation protocol on aromatic ketones and imines.

The Discovery of Quinoxaline-Based Metathesis Catalysts from Synthesis of Grazoprevir (MK-5172)

Olefin metathesis (OM) is a reliable and practical synthetic methodology for challenging carbon-carbon bond formations. While existing catalysts can effect many of these transformations, the synthesis and development of new catalysts is essential to increase the application breadth of OM and to achieve improved catalyst activity. The unexpected initial discovery of a novel olefin metathesis catalyst derived from synthetic efforts toward the HCV therapeutic agent grazoprevir (MK-5172) is described. This initial finding has evolved into a class of tunable, shelf-stable ruthenium OM catalysts that are easily prepared and exhibit unique catalytic activity.
