METHOD FOR PRODUCING N-MONOALKYL-SUBSTITUTED ALKYLENE AMINE
PROBLEM TO BE SOLVED: To provide a method for producing an N-monoalkyl-substituted alkylene amine especially useful for uses such as medicine intermediates, agrochemical intermediates, urethane resin-foaming catalysts, surfactants and the like among alkyl-substituted alkylene amine compounds from an alcohol and an alkylene amine as raw materials. SOLUTION: This method for producing the N-monoalkyl-substituted alkylene amine is characterized by reacting the alkylene amine with a ≥2C alkyl alcohol in the presence of a copper-containing oxide catalyst system. The N-monoalkyl-substituted alkylenamine is produced in high conversion and in N-monoalkylation selectivity.

Nucleophilic Ring Opening of 2-Oxazolines with Amines: A Convenient Synthesis for Unsymmetrically Substituted Ethylenediamines
The reaction of 2-alkyl-2-oxazolines with alkyl- and arylamines was investigated.The acid-catalyzed nucleophilic ring opening of the 2-oxazolines yields N-(2-aminoethyl)carboxamides in good to excellent yields with secondary amines and hindered primary amines.The N-(2-aminoethyl)carboxamides were hydrolyzed under acidic or basic conditions to selectively yield unsymmetrically substituted ethylenediamines.
