Three-Component C1 Alkynylation of Tetrahydroisoquinolines Catalyzed by Silver Acetate

A highly efficient method to fulfil the three-component C1 alkynylation of tetrahydroisoquinolines catalyzed by silver acetate was developed. This method features excellent regioselectivity and mild reaction conditions, is oxidant free, and can be performed in air. The power of this methodology was demonstrated by the rapid construction of the core structure of the natural product (tetrahydroberberine).

Regio- and chemoselective Csp3-H arylation of benzylamines by single electron transfer/hydrogen atom transfer synergistic catalysis

We present a highly regio- and chemoselective Csp3-H arylation of benzylamines mediated by synergy of single electron transfer (SET) and hydrogen atom transfer (HAT) catalysis. Under well precedented SET catalysis alone, the arylation reaction of N,N-dimethylbenzylamine proceeded via aminium radical cation formation and selectively targeted the N-methyl group. In contrast, addition of PhC(O)SH as a HAT catalyst precursor completely switched the regioselectivity to Csp3-H arylation at the N-benzylic position. Measurement of oxidation potentials indicated that the conjugate base of PhC(O)SH is oxidized in preference to the substrate amine. The discovery of the thiocarboxylate as a novel HAT catalyst allowed for the selective generation of the sulfur-centered radical, so that the N-benzyl selectivity was achieved by overriding the inherent N-methyl and/or N-methylene selectivity under SET catalysis conditions. While visible light-driven alpha-C-H functionalization of amines has mostly been demonstrated with aniline derivatives and tetrahydroisoquinolines (THIQs), our method is applicable to a variety of primary, secondary and tertiary benzylamines for efficient N-benzylic C-H arylation. Functional group tolerance was high, and various 1,1-diarylmethylamines, including an alpha,alpha,alpha-trisubstituted amine, were obtained in good to excellent yield (up to 98%). Importantly, the reaction is applicable to late-stage functionalization of pharmaceuticals.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Safety of 2-Methyl-1,2,3,4-tetrahydroisoquinoline, you can also check out more blogs about1612-65-3

Asymmetric Transfer Hydrogenation in Thermomorphic Microemulsions Based on Ionic Liquids

A thermomorphic ionic-liquid-based microemulsion system was successfully applied for the Ru-catalyzed asymmetric transfer hydrogenation of ketones. On the basis of the temperature-dependent multiphase behavior of the targeted microemulsion, simple product separation as well as catalyst recycling could be realized. The use of water-soluble ligands improved the immobilization of the catalyst in the microemulsion phase and significantly decreased the catalyst leaching into the organic layer upon extraction of the product. Eventually, the optimized microemulsion system could be applied to a wide range of aromatic ketones that were reduced with good isolated yields (up to 98%) and enantioselectivities (up to 97%), while aliphatic ketones were less successful.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 22990-19-8, help many people in the next few years.Computed Properties of C15H15N

The bicyclic isoxazolidine scaffolds are the ubiquitously recurring motifs in alkaloids. Despite of their facile biosynthesises in nature, the laboratory synthesis of these derivatives is still complicated. In this paper, the isoxazolidine derivatives are concisely constructed in one process with excellent stereoselectivity from simple tertiary amines through a C-H activation-retro-aza-Michael-oxidation-cyclization tandem sequence by means of visible-light. This protocol provides a concise approach to dactylicapnosinine derivatives.
