1,3-Dienic or styryl α-amino acid precursors and are easily obtained through the catalytic carbopalladation of allenes followed by the trapping of the intermediate π-allyl complex with either the anion of Schiff base or of acetamidomalonate .

Several approaches to the synthesis of derivatives of the antifungal antibiotic TAN-950A, which is also an agonist of glutamate at hippocampal neurons, are reported. Additions of isoxazolon-4-yl anions to methyleneoxazolidinones were not useful because addition occurred predominantly through N-2. Similarly addition of the isoxazolon-4-yl radicals to model Michael acceptors occurred predominantly through
