Front Cover: Catalytic Asymmetric Hydrogenation of Dehydroamino Acid Esters with Biscarbamate Protection and Its Application to the Synthesis of xCT Inhibitors (Chem. Eur. J. 20/2019)

Abstract

A new cystine-glutamate exchanger inhibitor was created through the development of a new catalytic asymmetric synthesis method. Rh-catalyzed catalytic asymmetric hydrogenation of dehydro amino acid esters was expanded to the synthesis of chiral amino acid esters with bis-carbamate protection. The new chemistry was successfully applied to the synthesis of N-benzoyl diamino suberic acid, which showed potent inhibitory effects for cystine-glutamate exchangers, a promising molecular target for cancer therapy.
