Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 130929-57-6, Name is (E)-2-cyano-3-(3,4-dihydroxy-5-nitrophenyl)-N,N-diethylacrylamide, SMILES is O=C(N(CC)CC)/C(C#N)=C/C1=CC([N+]([O-])=O)=C(O)C(O)=C1, belongs to indole-building-block compound. In a document, author is Cooksey, John P., introduce the new discover, Application In Synthesis of (E)-2-cyano-3-(3,4-dihydroxy-5-nitrophenyl)-N,N-diethylacrylamide.
Oxidative Pictet-Spengler cyclisations through acceptorless iridium-catalysed dehydrogenation of tertiary amines
The valuable tetrahydro-beta- and gamma-carboline skeleta can be accessed through Pictet-Spengler cyclisation initiated by acceptorless dehydrogenation of saturated cyclic amines. The substrate scope for the beta-isomers is found to be somewhat limited, but access to the gamma-isomers through the more reactive 2(aminoethyl)indoles is more general. The synthetic utility of hydrogen transfer catalysis is highlighted in a two-step preparation of the alkaloid desbromoarborescidine A by sequential redox-neutral alkylation/ de hyd roge native cyclisation.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.
