Facile and straightforward syntheses of both enantiomersof azetidine-2-carboxylic acid are described. The synthesesdepart from inexpensive chemicals and allow for the production, in five to six steps, of practical quantities of eachenantiomer. Synthetic highlights include the constructionof the azetidine ring using an intramolecular alkylation andthe use of optically active α-methylbenzylamine as chiralauxiliary.
