• The reductive condensation of L-valine with propionaldehyde in the presence of silk-palladium catalyst gave a mixture consisting of corresponding N-n-propyl and N, N-di-n-propyl derivatives. In the similar reaction with n-butyraldehyde, only N-n-butyl-L-valine was precipitated in an almost pure state owing its insolubility. The reductive methylation of N-n-propyl or N-n-butyl L-valine were effected with good results. The N-oxides were satisfactorily synthesized by the oxidation of corresponding N-methyl-N-alkyl-L-valine with an aqueous mixture of hydrogen peroxide and acetic acid.
