In this study we report the identification of a novel class of ligands for palladium-catalyzed C(sp3 )-H activation that enables the direct alkynylation of free carboxylic acid substrates. In contrast to previous synthetic methods, no introduction/re

The controlled construction of defined oxidation patterns is one of the key aspects in the synthesis of natural products and bioactive molecules. Towards this goal, we herein report a novel protocol for the Pd-catalyzed direct β-C(sp3)-H acetoxylati

We report the ligand enabled C(sp3)–H activation/olefination of free carboxylic acids in the γ-position. Through an intramolecular Michael-addition, δ-lactones are obtained as products. Two distinct ligand classes are identified that enable the c

A generally applicable Pd-catalyzed protocol for the β-C(sp3 )-H arylation of propionic acid and related α-branched aliphatic acids is reported. Enabled by the use of N-acetyl-β-alanine as ligand our protocol delivers a broad range of arylation pr
