An efficient synthesis of 1-acyl-3-arylimidazolidines catalyzed by montmorillonite K-10 clay under microwave irradiation
The synthesis of 1-acyl-3-arylimidazolidines were performed by reaction of N-acyl-N'-arylethylenediamines with formaldehyde and Montmorillonite clay K-10 as a catalyst under microwave irradiation.

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.
