Homochiral (alphaMe)Leu/Ala and Leu/Ala model peptides were synthesized by solution methods and fully characterized.A solution conformational analysis of the tripeptides was carried out using FT-IR absorbtion and 1H NMR.The crystal-state structure of Z-D-(alphaMe)Leu-(D-Ala)2-OMe monohydrate was resolved by X-ray diffraction.The results obtained support the conclusion that the tendency of the non-coded (alphaMe)Leu residue to fold into beta-bends and helical structures is markedly higher than that of its unmethylated protein counterpart (Leu).

Despite many efforts, one of the smallest heterocycles containing two nitrogen atoms, pyridazine, could not be converted to its N,N-dioxide (see, however, Nakadate et al. Chem. Pharm. Bull. 1970, 18, 1211-1218). HOF·CH3CN, made easily from diluted fluorine, was able to accomplish this task in a fast reaction with good yields.

[Ru2Cl(L)(CH3CN)4](PF6) 3 (1, L = 3,6-bis(N-(pyridylmethyl)imidazolylidenyl)pyridazine), [Cu3La3](PF6)3 (2, L a = 3-(N-(pyridylmethyl)imidazolylidenyl)-6-(N-(pyridylmethyl) imidazolylonyl)pyridazine), [Pd2(allyl)2L](PF 6)2 (3), [Pd2(allyl)2L b2](PF6)2 (4, Lb = N-pyridylmethylimidazole), and [NiLc2](PF 6)2 (5, Lc = 3-(N-(pyridylmethyl) imidazolylidenyl)-6-methoxylpyridazine) have been synthesized and fully characterized by NMR spectroscopy, elemental analysis, and X-ray diffraction analysis. In complex 1, ligand L binds to two Ru(II) centers, forming a well-behaved Ru2(L)Cl plane with a five-membered metallocyclic ring. Complex 2 is trinuclear, containing a triangular Cu3 unit bonded together by three 3-(N-(pyridylmethyl)imidazolylidenyl)-6-(N-(pyridylmethyl) imidazolylonyl)pyridazine, where one imidazolylidene was oxidized into imidazolone. Deprotonation reaction with Ag2O in CH3CN and CH3OH resulted in C-N cleavage of the imidazolium salt, and subsequent reaction with [Pd(allyl)Cl]2 and Ni(PPh3) 2Cl2 gave 4 and 5, respectively. Dinuclear Ru(II)-NHC complex 1 exhibits excellent catalytic activity for the oxidation of alkenes into diketones.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Computed Properties of C4H2Cl2N2, you can also check out more blogs about141-30-0
