Copper-catalyzed condensation of imines and alpha-diazo-beta-dicarbonyl compounds: modular and regiocontrolled synthesis of multisubstituted pyrroles

In the presence of a copper(ii) catalyst, enolizable imines bearing various N-substituents and alpha-diazo-beta-ketoesters undergo denitrogenative and dehydrative condensation to afford highly substituted pyrroles in moderate to good yields with exclusive regioselectivity. The reaction likely involves nucleophilic addition of the imine nitrogen to a copper carbenoid, tautomerization of the resulting azomethine ylide to an alpha-enaminoketone, and a subsequent enamine-ketone cyclocondensation. With Yb(OTf)3 as a unique cocatalyst, alpha-diazo-beta-diketones also participate in the same condensation reaction. The present reaction is applicable to acyclic, exocyclic, and endocyclic imines with tolerance of a broad range of functional groups and heterocyclic moieties, thus opening a new convenient route for the synthesis of the lamellarin family of natural products.

Rapid Synthesis of Aryl Fluorides in Continuous Flow through the Balz?Schiemann Reaction

The Balz?Schiemann reaction remains a highly utilized means for preparing aryl fluorides from anilines. However, the limitations associated with handling aryl diazonium salts often hinder both the substrate scope and scalability of this reaction. To address this, a new continuous flow protocol was developed that eliminates the need to isolate the aryl diazonium salts. The new process has enabled the fluorination of an array of aryl and heteroaryl amines.

Imine reductase based all-enzyme hydrogel with intrinsic cofactor regeneration for flow biocatalysis

All-enzyme hydrogels are biocatalytic materials, with which various enzymes can be immobilized in microreactors in a simple, mild, and efficient manner to be used for continuous flow processes. Here we present the construction and application of a cofactor regenerating hydrogel based on the imine reductase GF3546 from Streptomyces sp. combined with the cofactor regenerating glucose-1-dehydrogenase from Bacillus subtilis. The resulting hydrogel materials were characterized in terms of binding kinetics and viscoelastic properties. The materials were formed by rapid covalent crosslinking in less than 5 min, and they showed a typical mesh size of 67 ¡À 2 nm. The gels were applied for continuous flow biocatalysis. In a microfluidic reactor setup, the hydrogels showed excellent conversions of imines to amines for up to 40 h in continuous flow mode. Variation of flow rates led to a process where the gels showed a maximum space-time-yield of 150 g.(L.day)-1 at 100 muL/min.

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.Quality Control of 6,7-Dimethoxy-1-methyl-3,4-dihydroisoquinoline, you can also check out more blogs about4721-98-6

Removal of the pyrrolidine substituent by dehydrogenation of 4-pyrrolidin-2-yl-3,4-dihydro- and 1,2,3,4-tetrahydroisoquinolines

Pyrrolidin-2-yl-groups located at C-4 of 3,4-dihydro- or 1,2,3,4-tetrahydroisoquinolines, respectively, are lost in the course of dehydrogenation of these isoquinoline derivatives. However, acyclically substituted isoquinolines, hydrogenated in ring B, 2-benzyl-4-(1-dimethylaminoethyl)-1,2,3,4-tetrahydroisoquinoline, e.g., show loss of the amine group only by benzylic cleavage, affording 4-ethylisoquinoline. Scope and limitation of this reaction are determined using specifically substituted isoquinolines.
