Organo-Photoredox Catalyzed Oxidative Dehydrogenation of N-Heterocycles

We report here for the first time the catalytic oxidative dehydrogenation of N-heterocycles by a visible-light organo-photoredox catalyst with low catalyst loading (0.1?1 mol %). The reaction proceeds efficiently under base- and additive-free conditions with ambient air at room temperature. The utility of this benign approach is demonstrated by the synthesis of various pharmaceutically relevant N-heteroarenes such as quinoline, quinoxaline, quinazoline, acridine, and indole.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. HPLC of Formula: C9H7NO, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1074-88-0, in my other articles.

A heterogeneous gold(I)-catalyzed cascade annulation of aldehydes with propargylamine leading to 3-substituted 2,5-dimethylpyrazines

A heterogeneous gold(I)-catalyzed cascade annulation reaction of aldehydes with propargylamine was achieved in 1,2-dichloroethane at 40 C by using an MCM-41-immobilized phosphine gold(I) complex[MCM-41-PPh3-AuNTf2] as catalyst, yielding a variety of 3-substituted 2,5-dimethylpyrazines in good to excellent yields. The new heterogeneous gold(I) catalyst can easily be prepared via a simple procedure from commercially readily available reagents, and recovered by filtration of the reaction solution and recycled at least eight times without significant loss of activity.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1074-88-0,1H-Indole-7-carbaldehyde,as a common compound, the synthetic route is as follows.

EXAMPLE I 1-methyl-1H-indole-7-carbaldehyde 20 g 1H-indole-7-carbaldehyde are dissolved in 160 ml N,N-dimethylformamide and combined batchwise with 15.5 g potassium-tert.-butoxide under argon. After the addition has ended the mixture is left for 20 minutes with stirring and then 8.7 ml methyl iodide are added dropwise. Then the mixture is left for 12 hours at ambient temperature with stirring and then distributed between water and ethyl acetate. The aqueous phase is twice extracted with ethyl acetate and the combined organic phases are washed with saturated aqueous sodium chloride solution. After drying with magnesium sulphate the solvents are eliminated in vacuo. The residue is extracted from water. The solid thus obtained is suction filtered and dried in vacuo. Yield: 20 g (91% of theory) Mass spectrum (ESI+): m/z=160 [M+H]+
