Zhang, Yunfei;Sim, Jae Hun;MacMillan, Samantha N.;Lambert, Tristan H. research published 《 Synthesis of 1,2-Dihydroquinolines via Hydrazine-Catalyzed Ring-Closing Carbonyl-Olefin Metathesis》, the research content is summarized as follows. The synthesis of 1,2-dihydroquinolines by the hydrazine-catalyzed ring-closing carbonyl-olefin metathesis (RCCOM) of N-prenylated 2-aminobenzaldehydes is reported. Substrates with a variety of substitution patterns are shown. With an acid-labile protecting group on the nitrogen atom, in situ deprotection and autoxidation furnish quinoline. In comparison with related oxygen-containing substrates, the cycloaddition step of the catalytic cycle is shown to be slower, but the cycloreversion is found to be more facile.
870-50-8, Di-tert-butyl azodicarboxylate, also known as Di-tert-butyl azodicarboxylate, is a useful research compound. Its molecular formula is C₁₀H₁₈N₂O₄ and its molecular weight is 230.26 g/mol. The purity is usually 95%.
Di-tert-butyl azodicarboxylate is a reagent used in the electrophilic amination of β-keto esters catalyzed by an axially chiral guanidine. Building block in an enantioselective synthesis of 3,6-dihyropyridazines employing organocatalysts such a L-proline or (S)-2-pyrrolidinyl tetrazole. Utilized in the asymmetric Friedel-Crafts amination via a chiral organocatalyst.
Di-tert-butyl azodicarboxylate is a reagent used in the preparation of acyl hydrazinedicarboxylates via photoorganocatalytic hydroacylation of dialkyl azodicarboxylates with aldehydes in presence of phenylglyoxylic acid as photocatalyst., Formula: C10H18N2O4
