Reaction Steps

β-substituted-β-amino-acids were prepared by refluxing the corresponding benzaldehyde derivatives with excess ammonium acetate (˜2 equiv.), and malonic acid (1 equiv.) in absolute ethanol until the reaction has completed (determined by TLC and NMR). Cinnamic acid derivative was produced as a side product. The reaction mixtures were then workup with standard procedures, e.g., as described in FIG. 4.
