Ligand-Accelerated Iron Photocatalysis Enabling Decarboxylative Alkylation of Heteroarenes

A mild, practical protocol for the decarboxylative alkylation of heteroarenes has been accomplished via iron photocatalysis. A diverse range of carboxylic acids readily undergo oxidative decarboxylation and then couple with a broad array of heteroarenes in this transformation. The photoexcited state lifetimes of iron complexes are typically much shorter than those of iridium and ruthenium complexes. Here we describe our effort on iron photocatalysis by utilizing the intramolecular charge transfer pathway of iron-carboxylate complexes.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 34784-05-9, and how the biochemistry of the body works.Reference of 34784-05-9

Synthesis and DNA binding properties of novel benzo[b]isoquino|2,3-h- naphthyridines

Several benzo[b]isoquino[2,3-h]-naphthyridines have been prepared via formal hetero-Diels Alder reaction of N-aryl imines as a key step. These compounds have different side chains at C-11, and a cis or trans configuration at the C-8a,C-14a ring junction. Binding constants for the interaction with oligonucleotides and polynucleotides were determined by UV absorption and melting experiments. NMR experiments (NOE) revealed that the cis isomers, showing a slightly folded structure, preferentially bind to the minor groove of AT-rich oligomers. In contrast, the trans isomers prefer the CG-rich sequences, leading to cap-complexes with the isoquinoline moiety stacked at the top of the double helix, in agreement with the flatter shape, and with a preference for the 3?-terminals, as found for camptothecins. Models of the complexes were built up by molecular dynamics (MD) calculations, by using the inter-proton distances derived from the NOE values. Cytotoxicity assays against human Ewing sarcoma cell lines RD-ES and CAD-ES1 were performed. The Royal Society of Chemistry 2005.

Trichlorophenyl formate: Highly reactive and easily accessible crystalline CO surrogate for palladium-catalyzed carbonylation of aryl/alkenyl halides and triflates

The high utility of 2,4,6-trichlorophenyl formate, a highly reactive and easily accessible crystalline CO surrogate, is demonstrated. The decarbonylation with NEt3 to generate CO proceeded rapidly at rt, thereby allowing external-CO-free Pd-catalyzed carbonylation of aryl/alkenyl halides and triflates. The high reactivity of the CO surrogate enabled carbonylation at rt and significantly reduced the quantities of formate to near-stoichiometric levels. The obtained trichlorophenyl esters can be readily converted to a variety of carboxylic acid derivatives in high yields.
