We report herein the first use of N-chloroimines as effective synthons for directed C-H functionalization. Rh(III)-catalyzed coupling of N-chloroimines with alpha-diazo-alpha-phosphonoacetates allows for efficient dechlorinative/dephosphonative access to 2H-isoindoles. Further deesterification under Ni(II) catalysis enables the complete elimination of reactivity-assisting groups and full exposure of reactivity of C3 and N2 ring atoms for attaching structurally distinct appendages.

The development of efficient and eco-friendly methods for the synthesis of elaborate amines is highly desired as they are valuable chemicals. The catalytic alkylation of amines using alcohols as alkylating agents, through the so-called borrowing hydrogen process, satisfies several of the principles of green chemistry. In this paper, four neutral half-sandwich complexes of Ru(II), Rh(III), and Ir(III) have been synthesized and tested as catalysts in theN-benzylation of amines with benzyl alcohol. The new derivatives contain aN(boolean AND)N ‘ anionic ligand derived from 5-(pyridin-2-ylmethylene)hydantoin (Hpyhy) that has never been tested in metal complexes with catalytic applications. In particular, the Ir derivatives, [(Cp*)IrX(pyhy)] (X = Cl or H), exhibit high activity along with good selectivity in the process. Indeed, the scope of the optimized protocol has been proved in the benzylation of several primary and secondary amines. The selectivity towards monoalkylated or dialkylated amines has been tuned by adjusting the amine:alcohol ratio and the reaction time. Experimental results support a mechanism consisting of three consecutive steps, two of which are Ir catalyzed, and a favorable condensation step without the assistance of the catalyst. Moreover, an unproductive competitive pathway can operate when the reaction is performed in open-air vessels, due to the irreversible release of H-2. This route is hampered when the reaction is carried out in close vessels, likely because the release of H(2)is reversed through metal-based heterolytic cleavage. From our viewpoint, these results show the potential of the new catalysts in a very attractive and promising methodology for the synthesis of amines.

Proton transfer processes mediate many organic reactions. How to realize stereochemical control of this process has always been a challenging topic in the field of asymmetric catalysis. In this study, N-(diphenylmethyl)-1-phenylethan-1-imine (Schiff base derived from 2,2-diphenylethan-1-amine and acetophenone) was used as substrate, and different near neutral solvents and various chiral metal complex catalysts were used to carry out photoinduced C=N double bond transfer in the substrate under irradiation with a mercury ultraviolet lamp. The double bond transfer in the substrate molecule was highly selective. Solvents containing strong electronegative atoms like oxygen and chlorine, such as alcohols, aldehydes, and carbon tetrachloride, were more effective than other solvents under high light intensity. The 1,3-proton transfer process involves photoexcitation of the Schiff base and coordination of the latter to the central metal atom of the chiral catalyst, so that the substrate molecule is placed in a stable chiral environment to form a transition state. The strongly electronegative atom of the near-neutral solvent attracts the active a-hydrogen from the excited Schiff base molecule to form a negatively charged delocalized p-bond structure. The subsequent proton addition yields more stable molecular structure to complete the selective proton transfer process. Among the examined chiral catalysts, divalent tin porphyrin was the most effective, and the product yield and enantiomeric excess were 98% and 91.49%, respectively. The described photoinduced C=N double bond transfer in N-(diphenylmethyl)-1-phenylethan-1-imine is characterized by mild conditions (room temperature), high stereoselectivity, and simple operation.

Several phenoxy-imine ligands bearing o-trityl group in phenoxy moiety RN=CHArOH (Ar = C6H2(CPh3)Bu-t, R = 2,6-Me2C6H3 (L1H); 2,6-(Pr2C6H3)-Pr-i (L2H); 3,5-(CF3)(2)C6H3 (L3H); 3,5-(OMe)(2)C6H3 (L4H); CHPh2 (L5H); CPh3 (L6H)) were synthesized and characterized by H-1 NMR and C-13 NMR spectroscopy. The vanadium complexes based on these ligands LVCl2(THF)(2) (1-6) were synthesized via conventional transmetalation reaction in moderate to high yields. Complexes 1-6 were fully characterized by FT-IR, elemental analyses and the molecular structures of 1, 2 center dot H2O, (2 center dot H2O)(2)(mu-Cl)(2), 4, and 5 were confirmed by X-ray crystallographic analysis in which the six-coordinated vanadium centers are in a typical octahedral geometry. Upon activation with Et2AlCl in toluene, complexes 1-6 showed high activities in ethylene polymerization affording polymers with moderate molecular weight (5.9-11.8 x 10(4) Da). Moreover, in hexane or CH2Cl2, 1-6/Et2AlCl exhibited enhanced activities. When activated with MAO or MMAO in toluene, these complexes showed relatively low activities but afforded polymers with ultra-high molecular weight (up to 3.30 x 10(6) Da). 1-6/Et2AlCl also showed high activities in ethylene/1-hexene copolymerization at room temperature giving moderate molecular-weight polymers (6.5-11.4 x 10(4) Da) with co-monomer incorporation being of 6.0 similar to 7.8%.

Category: amides-buliding-blocks. I found the field of Chemistry very interesting. Saw the article Absolute asymmetric Strecker synthesis in a mixed aqueous medium: reliable access to enantioenriched alpha-aminonitrile published in 2019.0, Reprint Addresses Kawasaki, T (corresponding author), Tokyo Univ Sci, Dept Appl Chem, Shinjyuku Ku, Tokyo 1628601, Japan..

Without using chiral sources, the Strecker reaction of achiral hydrogen cyanide, p-tolualdehyde and benzhydrylamine gave enantioenriched L- or D-N-benzhydryl-alpha-( p-tolyl) glycine nitriles with up to > 99% ee in a mixed solvent of water and methanol. Therefore, total spontaneous resolution of alpha-aminonitriles could occur through a prebiotic mechanism of alpha-amino acid synthesis. Moreover, it was demonstrated that the repetition of partial dissolution and crystallization of a suspended conglomerate of aminonitrile under solution-phase racemization could generate the enantiomeric imbalance to afford, in combination with the amplification of chirality, an enantioenriched product in every case. Among the 73 experiments that were carried out, D-and L-enriched isomers occurred 36 and 37 times, respectively. This stochastic behavior, under achiral or racemic starting conditions, meets the requirements of the spontaneous absolute asymmetric Strecker synthesis. The implications of the present results for the origin of chirality of alpha-amino acids are discussed.

Enantioselective reduction of ketimines was demonstrated using chiral N-heterocyclic carbene (NHC)-stabilised borenium ions in frustrated Lewis pair catalysis. High levels of enantioselectivity were achieved for substrates featuring secondary N-alkyl substituents. Comparative reactivity and mechanistic studies identify key determinants required to achieve useful enantioselectivity and represent a step forward in the further development of enantioselective FLP methodologies.

The metal-catalyzed dehydrogenative coupling of alcohols and amines to access amides has been recognized as an atom-economic and environmental-friendly process. Apart from the formation of the amide products, three other kinds of compounds (esters, imines and amines) may also be produced. Therefore, it is of vital importance to investigate product distribution in this transformation. Herein, N-heterocyclic carbene-based Ru (NHC/Ru) complexes [Ru-1]-[Ru-5] with different ancillary ligands were prepared and characterized. Based on these complexes, we selected condition A (without an added NHC precursor) and condition B (with an added NHC precursor) to comprehensively explore the selectivity and yield of the desired amides. After careful evaluation of various parameters, the Ru loadings, added NHC precursors and the electronic/steric properties of ancillary NHC ligands were found to have considerable influence on this catalytic process.
