Organoselenium-Catalyzed Aza-Wacker Reactions: Efficient Access to Isoquinolinium Imides and an Isoquinoline N-Oxide

An efficient approach for the organoselenium-catalyzed aza-Wacker reaction of olefinic hydrazones and an oxime to form isoquinolinium imides and an isoquinoline N -oxide is developed. This transformation involves a direct intramolecular C-H amination using hydrazones and an oxime as imine-type nitrogen sources. This work not only provides a new approach for the construction of isoquinoline derivatives, but also expands the scope of nitrogen sources in electrophilic selenium catalysis.

Application of 2038-03-1, Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 2038-03-1.

Studies on the Respective Reactions of Quinoline and Isoquinoline with Transient Species by Pulse Radiolysis

Respective reactions of quinoline and isoquinoline with typical oxidative/reductive transient species, i.e., hydrated electrons, hydroxyl radicals, and hydrogen atoms (obtained after the reaction of an electron beam by proper condition-controlling) were investigated by pulse radiolysis. Absorption spectra of the transient products and their change trends were investigated. Reaction rate constants of hydrated electrons with quinoline and isoquinoline were 7.1×10(9) and 3.4×10(9) mol(-1).L.s(-1), respectively. The hydroxyl radical had rate constants of 7.2×10(9) and 3.4×10(9) mol(-1).L.s(-1), respectively. The rate constants of hydrogen atoms were 5.7×10(9) and 3.6×10(9) mol(-1).L .s(-1), respectively. Results showed that both quinoline and isoquinoline reacted with hydrated electrons, hydroxyl radicals, and hydrogen atoms very quickly. However, reaction rates of quinoline with these transient reductive/oxidative species were faster than that of isoquinoline. Stabilities of the transient products from these reactions were analyzed by electron theory. Reaction products from quinoline’s reaction with transient species were found to be more stable than reaction products from the isoquinoline reaction and this difference was the reason for the difference in rate constants.

The cyclization reaction of ortho-ethynylbenzaldehyde derivatives into isoquinoline derivatives

In order to elucidate the reaction mechanism of the cyclization between an ethynyl group and an imino group at the ortho-position on an aromatic ring to afford isoquinolines, reaction of 2-ethynylbenzaldehydes under various conditions was examined. It is concluded that reaction proceeds via an ionic process and the isoquinoline 4-hydrogen atom derives from the solvent. In addition, it was found that 2-ethynylbenzaldehyde O-methyloximes underwent cyclization in the presence of primary and secondary alcohols to give 3-substituted isoquinolines.
