Unrestricted: Pseudoephenamine is introduced as a versatile chiralauxiliary and an alternative to pseudoephedrine in asymmetricsynthesis. It is free from regulatory restrictions and leads to remarkable stereocontrol in alkylation reactions, especially in those that form quaternary carbon centers. Amides derived from pseudoephenamine exhibit a high propensity to be crystalline substances, and provide
