The direct β-selective hydrocarboxylation of styrenes under atmospheric pressure of CO2 has been developed using photoredox catalysis in continuous flow. The scope of this methodology was demonstrated with a range of functionalized terminal styrenes, as well as α-substituted and β-substituted styrenes.

A palladium-catalyzed dearomatizing difunctionalization of N-Boc-indoles and benzofurans to give tricyclic indolines and 2,3-dihydrobenzofurans with a fully substituted carbon center is described. Product formation occurs under mild conditions at room temperature with commercially available aryl boronic acids and 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) as a mild oxidant in good yields. 2-Carboxyalkyl-substituted indoles and benzofurans react under Pd-catalysis with aryl boronic acids and TEMPO through dearomatizing arylation/cyclization to the corresponding indolines and dihydrobenzofurans containing a lactone moiety bearing a fully substituted carbon center.

A Ru-catalyzed direct thermal trifluoromethylation and perfluoroalkylation of N-acyloxazolidinones has been developed. The reaction is experimentally simple and requires inexpensive reagents while providing good yields of products with good levels of stereocontrol. Preliminary studies have shown notable compatibility with functional groups, aromatics, and certain heteroaromatic substituents. The described method provides a useful alternative for the synthesis of fluorinated materials in an experimentally convenient manner.
Syntheses of Furano Compounds: Part XLIV. Syntheses of 2-CarboxybenzoFuran-3-Acetic Acid and 3-CarboxybenzoFuran-2-Acetic Acid
