Decarboxylative Csp3 -N Bond Formation by Electrochemical Oxidation of Amino Acids

Decarboxylative Csp3-N coupling reactions have been developed through electrochemical oxidation of amino acids. The reaction proceeds via anodic oxidative decarboxylation of carboxylic acids to form stabilized carbocations, which are trapped by azoles or amides to construct C-N bonds. This method avoids the preactivation of carboxylic acids and the use of expensive transition-metals and external chemical oxidants.

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 497-25-6 is helpful to your research. Application of 497-25-6

Iridium-catalyzed enantioselective allylic alkylation using chiral phosphoramidite ligand bearing an amide moiety

New chiral phosphoramidites with an amide moiety were used for iridium-catalyzed asymmetric allylic alkylation reactions. The best results were obtained with a ligand bearing an oxazolidinone moiety. The reaction of cinnamyl acetate with diethyl sodiomalonate without the use of lithium chloride gave the branched product with 94% ee.

Metallations and reactions with electrophiles of 4-isopropyl-5,5-diphenyloxazolidin-2-one (DIOZ) with N-allyl and N-propargyl substituents: Chiral homoenolate reagents

N-Allyl, N-cinnamyl, and N-(3-trimethylsilyl)propargyl derivatives of 4-isopropyl-5,5-diphenyloxazolidin-2-one (DIOZ) are prepared by lithiation of the parent DIOZ (with BuLi in THF) and reaction with the corresponding bromides (Scheme 1). Lithiation in the same solvent, with deprotonation by BuLi on the allylic or propargylic CH2 group at dry-ice temperature, provides colorful solutions, which are either combined with aldehydes or ketones directly or after addition (with or without warming) of (Me2N)3TiCl or (i-PrO)3TiCl. Conditions have thus been elaborated under which all three types of conjugated lithium compounds react in the gamma-position with respect to the oxazolidinone N-atom: carbamoyl derivatives of enamines and allenyl amines are formed in yields ranging from 60 to 80% and with diastereoselectivities up to 98% (Schemes 2-5). The C= C bond of the N-hydroxyalkenyl groups has (Z)-configuration (products 5 and 8), the allene chirality axis has (M)-configuration (products 9), and the addition to aldehydes and unsymmetrical ketones has taken place preferentially from the Si face. A mechanistic model is proposed that is compatible with the stereochemical outcome (assuming kinetic control and disregarding the presence of Li and Ti species in the reaction mixture; cf. L, M in Fig. 4). Hydrolysis of the enamine derivatives leads to lactols, oxidizable to gamma-lactones, with recovery of the crystalline oxazolidinone, as demonstrated in three cases (Scheme 6). Thus, the application of chiral oxazolidinone auxiliaries (cf. Figs. 1 and 2) has been extended to the overall enantioselective preparation of homoaldols.

CISPLATIN COMPLEX AND PREPARATION METHOD THEREOF

A CDDP complex is formed by complexation of CDDP and a polymer having a structure of Formula (I). The CDDP complex has good biocompatibility and is degradable. A side chain of the polymer is grafted with polyethylene glycol, which gives the CDDP complex good dissolvability. When dissolved in an aqueous medium, the CDDP is protected by a hydrophilic polyethylene glycol chain segment and a hydrophobic amino acid chain segment, which can effectively avoid a sudden release of the CDDP due to the influence of the blood circulation system after intravenous injection, thus improving the stability of the CDDP complex. A carboxyl group contained in the CDDP complex has pH value sensitivity and tends to be deprotonated in a low pH environment, which is advantageous for promoting the release of a drug, and improving the efficiency of the drug.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 13590-42-6

Cobalt-Copper Catalyzed C(sp2) ? N Cross Coupling of Amides or Nitrogenated Heterocycles with Styrenyl or Aryl Halides

An efficient C(sp2) ? N cross coupling of cyclic and acyclic amides with styrenyl/aryl/heteroaryl halides catalyzed by cobalt acetylacetonate in combination with copper(I) iodide, has been achieved. A library of diversely substituted cyclic and acyclic enamides have been obtained in high yields by this procedure. The reaction is stereoselective producing (E)?enamides from trans-styrenyl halides and (Z)- products from cis-halides. This procedure has been successfully employed for the coupling of other N-heterocycles such as pyrazole, imidazole and triazole with aryl/styrenyl/heteroaryl halides to produce the corresponding N-coupled products. A probable mechanism has been suggested.
