Synthesis of β-Amino Acids and Derivatives by Carboxylation
In a palladium-catalyzed intermolecular aminocarbonylation of alkenes, the use of hypervalent iodine reagent can accelerate the reaction. The current transformation presents a convenient method to generate β-amino acid derivatives from simple alkenes.

A Ni-catalyzed reductive carboxylation of N-substituted aziridines with CO2 at atmospheric pressure provides β-amino acids, important building blocks with considerable potential as peptidomimetics. The protocol offers mild conditions, experimental ease, and exquisite chemo- and regioselectivity.
