Abstract
Abstract A practical and convenient synthesis of azetidine-3-carboxylic acid (1) that proceeded in 55% overall yield from commercially available diethylbis(hydroxymethyl)malonate (3) is reported. Azetidine ring-formation was achieved in high yield by cyclization of bistrifiate of the diol (3) and benzylamine. Decarboxylation under carefully pH-controlled conditions gave the mono acid azetidine that was hydrogenated to give the title compound.
