Abstract
AbstractIn this article, we describe the stereoselective formation of β,β‐disubstituted dehydroamino acids (ΔAAs) in peptides using a cationic rhodium catalyst and methyl trifluoroborate salt. Using this approach, an alkyl group was directly installed on a β‐monosubstituted ΔAA in the peptide chain and both isomers of dehydroisoleucine, an important yet usually inaccessible ΔAA, were successfully obtained.
