Synthesis of Arylethylamines via C(sp3)–C(sp3) Palladium-Catalyzed Cross-Coupling

Research published in The Journal of Organic Chemistry, from Lippa, R. et al., has shown the access to substituted arylethylamines that are key structural components in natural, pharmaceutical, and agrochemical compounds. Substituted phenylethylamine and structurally related analogues represent a key pharmacophore found in endogenous and synthetic neurotransmitters, pharmaceutical agents, and agrochemical products including products such

A Biomimetic SH2 Cross-coupling Mechanism for Quaternary sp3 – Carbon Formation

Recent work from the MacMillan group at Princeton University was published in Science Journal presenting a biomimetic SH2 cross-coupling mechanism for quaternary sp3-carbon formation. This study examined the cross-coupling between tertiary redox-active esters and primary alkyl bromides in the presence of Fe(OEP)Cl as an effective SH2 catalyst, in tandem with Iridium based photocatalyst and the

The Influence of Effect of Polysaccharides and Polyvinylpyrrolidone on the Photocatalytic Activity of Chlorin e6 in Tryptophan Oxidation

A.B. Solov’eva et. al recently demonstrated in the Russian Journal of Physical Chemistry A that the addition of poly-N-vinylpyrrolidone (PVP) and the polysaccharides sodium alginate (SA) and hyaluronic acid (HA) to chlorin e6 (Ce6) increases the photosensitizing activity of Ce6 in the reaction of tryptophan oxidation.  While PVP, HA, and SA do not exhibit intrinsic

Spectroscopic Study of Porphyrin Self-Assembly: Role of pH, Time and Chiral Template

The Mammana group at the University of Dayton recently reported the self assembly of charged porphyrins onto a chiral substrate in the Journal Chirality. Charged water soluble porphyrins were used to produce chiral self-assembled structures by templating on to  the chiral templates D or L polyglutamic acid.  The negatively charged porphyrin, meso-Tetra(4-sulfonatophenyl)porphine  cat. No. T1239,

General Access to C-Centered Radicals: Combining a Bioinspired Photocatalyst with Boronic Acids in Aqueous Media

Steven Bloom group present in ACS Catalysis a general catalytic platform to access diverse heteroaromatic radicals, aromatic and aliphatic radicals from commercial boronic acids using a cofactor-derived flavin photocatalyst in aqueous media. They showed the capability of these radicals to engage Michael acceptors via single-electron conjugate addition. In this method they demonstrated that water acts

Structure of a Zinc Porphyrin-Substituted Bacterioferritin and Photophysical Properties of Iron Reduction

Work from the Kurtz group at the University of Texas at San Antonio published in Biochemistry described the process by which Zn(II) protoporphyrin IX (ZnPP) complexes were generated and loaded with iron to determine both the photophysical and photochemical properties of the complex. The X-ray crystal structures obtained depicted a six-coordinate zinc in the ZnPP
