Nucleophilic addition reactions of free and enzyme-bound deazaflavin.
DeazaFMN-containing glycolate oxidase has been prepared and shown to catalyze the stereospecific transfer of the alpha-hydrogen from substrate to enzyme-bound deazaFMN. The reaction of sulfite, cyanide, and hydroxylamine with several deazaflavin-containing enzymes (glycolate oxidase, D-amino acid oxidase, glucose oxidase, N-methylglutamate synthetase) and free deazaFMN has been examined. All th...
متن کاملThe Role of Solvent Reorganization in Proton Transfer and Nucleophilic Addition Reactions
The factors believed to be of primary importance in determining the intrinsic barrier and affecting transition state structure in proton transfers at carbon are critically reviewed. They include the absence of strong hydrogen bonding between carbon and solvent and the occurrence of extensive structural and solvent reorganization in going from reactants to products. Structural and solvent reorga...

15 صفحه اولMechanistic study of secondary organic aerosol components formed from nucleophilic addition reactions of methacrylic acid epoxide
Recently, methacrylic acid epoxide (MAE) has been proposed as a precursor to an important class of isoprene-derived compounds found in secondary organic aerosol (SOA): 2-methylglyceric acid (2-MG) and a set of oligomers, nitric acid esters, and sulfuric acid esters related to 2-MG. However, the specific chemical mechanisms by which MAE could form these compounds have not been previously studied...
متن کاملReactions of Oxime Dianions: Stereospecificity in Alkylation
n carbon.L However, no information on the stereochemistry of the alkylated products was ever reported. We now wish to report total stereospecificity in the formation and alkylation of the a-carbon, oxygen-dianions of aliphatic ketoximes. Treatment of acetoxime 1 with two equivalents of n-BuLi in THF at O°C for 15 minutes resulted in the formation of exclusively the x dianion 2, which upon deute...
