Quaternary α-amino acids allow access to molecular structures and peptides derivatives with interesting biological activites. Many asymmetric synthesis are described in the literature. The most common one is the alkylation of tertiary α-amino acids. Only few methods use the chirality of the starting material as a chiral inductor. Among them, Memory of Chirality is one strategy allowing the access to enantioenriched quaternary α-amino acids using, as a unique source of chirality, the central initial chirality of tertiary α-amino acids. The objective of this PhD is the investigation of new methods for the quaternary α-amino acid synthesis by Memory of Chirality. Two main axes have been studied: 1) Oxidative heterocoupling of enolates by Memor...
