The invention includes procedures for stereoselective β-arylation of carboxylic acids having a β-carbon atom. For example, stereoselective arylation procedures include the following reactions: (I)
chiral ligand based on an ethylenediamine backbone was developed to achieve Pd-catalyzed enantioselective C(sp3)-H arylation of cyclopropanecarboxylic and 2-aminoisobutyric acids without using exogenous directing groups. This new chiral catalyst affords new disconnection for preparing diverse chiral carboxylic acids from simple starting materials that are complementary to the various ring forming approaches
