    16 - 115Direct Vinylation of 2-Substituted N-(Benzylidene)glycinonitrilesunder Basic Conditions. -Vinyl substituted nitriles (III), (V), and(VI) are prepared via addition of carbanions generated from nitriles (I) toacetylenes ( II) and (IV). However, all attempts to convert these products into. beta.,-unsaturated -amino acids fail. Only , -unsaturated ketones, e.g.(VII), are obtained.
