Mechanistic Studies on Bioinspired Aerobic C-H Oxidation of Amines with an ortho-Quinone Catalyst

We report herein our mechanistic studies of the ortho-quinone-catalyzed aerobic oxidation of primary, secondary, and tertiary amines. Two different catalytic pathways were discovered for the reductive half reactions: for primary amines, the reaction was found to proceed via a transamination pathway, while the reactions with secondary amines and tertiary amines proceeded via hydride transfer. We also found that the amine substrates could significantly promote the regeneration of the ortho-quinone catalyst in the oxidative half reaction, in which a proton transfer occurs between the amine substrates and catechol derivatives (the reduced form of the ortho-quinone catalyst).

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 1745-07-9 is helpful to your research. 1745-07-9

Photocatalyst- And transition-metal-free alpha-allylation of: N -aryl tetrahydroisoquinolines mediated by visible light

A convenient and efficient alpha-allylation of N-aryl tetrahydroisoquinolines has been achieved. This transformation can be realized under only visible light irradiation without the aid of transition metals or photocatalysts. The mechanism involves a novel in situ-generated electron-donor-acceptor (EDA) complex between the N-aryl tetrahydroisoquinolines and an allyl or a benzyl bromide. Irradiation with purple light triggered single-electron transfer (SET) from the N-aryl tetrahydroisoquinolines to the allyl or benzyl bromide of the EDA complex, inducing the formation of the corresponding allyl or benzyl radical and the subsequent radical-radical coupling. This approach represents the first example of a photocatalyst- and transition-metal-free alpha-allylic and benzylic functionalization of N-aryl tetrahydroisoquinolines.

Efficient construction of C=N double bonds via acceptorless dehydrogenative coupling

The efficient construction of C=N double bonds has been achieved by the Ir-catalyzed intramolecular acceptorless dehydrogenative cross-coupling of tertiary amines and amides. An iridium/2-hydroxypyridine complex was identified as the highly efficient catalyst. A number of quinazolinone derivatives was prepared in excellent yields. An iridium-mediated C-H activation mechanism is proposed. This finding provides an unprecedented strategy for the direct imidation of sp3 C-H bonds.

Visible-light-driven electrocyclization of activated allylic amines via azomethine ylide formation

Visible-light-driven aerobic oxidative 6pi-electrocylization of tetrahydroisoquinoline (THIQ) derived activated allylic amines leading to functionalized tricyclic N-heterocycles is reported. The reaction proceeds through visible-light-induced formation of the iminium ion followed by azomethine ylide generation, and cyclization steps. This is the first example of visible-light-initiated catalytic electrocyclization reaction at room temperature.
