The competing reaction involves the formation of imines (presumably via diradicals and hydrogen migration), as proposed by Logothetis to account for the formation of imines in the thermolysis of aziridines. Imine formation is sometimes observed as a competing pathway in the thermolysis of N-substituted vinylaziridines, and can also be rationalized by a process analogous to a [1,5.

Design of Axially Chiral Dicarboxylic Acid for Asymmetric Mannich Reaction of Arylaldehyde N-Boc Imines and Diazo Compounds Takuya Hashimoto and Keiji Maruoka* *Department of Chemistry, Graduate School of Science, Kyoto University, Sakyo, Kyoto , Japan, Email: maruoka The reaction mechanism was elucidated by mechanistic studies employing the mediation of the catalyst was an iron salt and the reaction worked also on racemic oxaziridines, the synthesis of N-alkyloxazolidinones 88 from N-alkylaminoethanol using nitric acid to activate the alcohol and the cyclisatjon of chiral 2. corresponding N-alkyl derivatives 3a-g by condensation with the corresponding aldehyde followed by in situ reduction of the obtained oxazolidine. These N-alkyl β-amino alcohols furnished cleanly the expected aziridines 4a-g upon treatment with tosyl chloride and triethylamine in the presence of catalytic amounts of DMAP (scheme 3).

Oxidative RNA damage is linked to cell dysfunction and diseases. The present work focuses on the in vitro oxidation of 5-methylaminomethyl uridine (mnm5U), which belongs to the numerous post-transcriptional modifications that are found in tRNA. The reaction of oxone with mnm5U in water at pH leads to two aldonitrone derivatives. They form by two oxidation steps and one dehydration by: 1. A highly stereoselective aza-Henry reaction of α-aryl nitromethanes with aromatic N-Boc imines was established by using C1 -symmetric chiral ammonium betaine as a bifunctional organic base catalyst. Various substituted aryl groups for both imines and nitromethanes were tolerated in the reaction, and a series of precursors for the synthesis of. Organotransition Metal Chemistry From Bonding to Catalysis provides a selective, but thorough and authoritative coverage of the fundamentals of organometallic chemistry, the elementary reactions of these complexes, and many catalytic processes occurring through organometallic intermediates.
