Abstract

Unnatural α,α-disubstituted α-amino acids have played a privileged role in drug discovery campaigns, and the development of their efficient synthetic methods has thus received continuous attention. This account describes our originally developed synthetic methods to obtain α,α-disubstituted α-amino acid derivatives using readily accessible building blocks.
