Abstract
PURPOSE: To prepare an N-acyl-α-amino acid in high yield with easy operations, by reacting an organic halide as a raw material in two layers of water and a water- immiscible solvent in the presence of a base, thereby separating the by-produced salt from the product.
CONSTITUTION: An N-acyl-α-amino acid of formula III is prepared by reacting an organic halide of formula I (R1 is organic residue; X is halogen), e.g. methyl halides, benzyl halides, etc., with CO and H2 in two layers of water and water- inmiscible organic solvent in the presence of a catalyst which comprises a transition metal belonging to the VIII group of the periodic table or a compound thereof, a carboxylic acid amide of formula II (R2 and R3 are H or organic residue; R1 and R2, R1 and R3, and R2 and R3 may form the same radical) having at least one H at N position, and a base.
