Analysis of crystallographic structures of Ni(II) complexes of alpha-amino acid Schiff bases: Elucidation of the substituent effect on stereochemical preferences

In this study, we performed critical analysis of 13 crystallographic structures of various Ni(ii) complexes of amino acid Schiff bases. The major finding of this work is the significance of a parallel displaced type of aromatic interactions between o-amino-benzophenone and Pro N-benzyl rings. The quality of these aromatic interactions was shown to control the steric environment around the amino acid side-chain, rendering variously substituted Ni(ii) complexes of different thermodynamic stabilities. The discovered structural trend holds true for aliphatic, aromatic and sterically bulky amino acids and can be used for the rational design of new and more efficient chiral ligands for general asymmetric synthesis of tailor-made alpha-amino acids.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 4442-59-5 is helpful to your research. Synthetic Route of 4442-59-5

Alkylations of chiral nickel(II) complexes of glycine under phase-transfer conditions

Alkylation reactions of nickel(II) complex 6 derived from glycine and 2-[(1-benzyl-L-prolyl)amino]benzophenone (BPBP) were studied under phase-transfer-catalysis (PTC) conditions. The goal of this work was to find an alternative suitable solvent for these reactions to replace the commonly used CH2Cl2 which leads to the formation of several by-products, thus lowering the yield of target compounds. We demonstrate that 1,2-dichloroethane is a markedly better solvent providing higher yields (75-99%) of the desired products 10 with 36-88% diastereoisomer purity (Scheme3 and Table). Furthermore, we show that the stereochemical outcome of these PTC reactions (kinetic control) can be easily improved to >95% de by treatment of the PTC products with MeONa/MeOH. The scope of these reactions includes alkylations with methyl iodide as well as activated halides such as benzyl, allyl or propargyl, bromides and most notably ethyl 2-bromoacetate (Table).
