Abstract
A novel method of an amidocarbonylation reaction among an aldehyde compound, an amide compound, and carbon monoxide, which comprises using a palladium-supporting crosslinked-polymer composition containing palladium clusters having a major-axis length of 20 nm or shorter to conduct the amidocarbonylation reaction. Thus, an N-acyl-α-amino acid can be more efficiently and selectively synthesized in a dean reaction system. Also provided is a catalyst for use in the method.
