Phenylacetaldehyde oxime, reduction

Phenylacetaldehyde oxime, reduction with lithium aluminum hydride,... 

Excellent yields of the oximes of phenylacetaldehydes are obtained by reduction of 6-nitrostyrenes over Pd-on-C in a pyridine solvent (74,75). The technique gives yields of only about 60% when applied to aliphatic unsaturated nitrocompounds better yields are obtained in acidic media(6 5). Over 5% Rh-on-Al203 in ethanol-acetic acid-ethyl acetate, 2- 6-dinitro-styrenes are converted to 2-nitrophenylacetaldehyde oximes (13). 

Phenylalanine has been prepared by the action of ammonia and hydrogen cyanide upon phenylacetaldehyde,1 by the reduction of the oxime of phenylpyruvic acid,2,3 by the action of ammonia on a-bromo-j3-phenylpropionic acid,4 and by the reduction of a-aminocinnamic add or its derivatives by means of sodium amalgam with water,5,6 or red phosphorus with hydriodic acid.7,8...
