✦ Synopsis

An efficient method for the selective synthesis of 2-substituted oxazines and tetrahydropyrimidines by the reaction of arylnitriles with 3-amino-1-propanol and 1,3-diaminopropane in the presence of montmorillonite K-10 and KSF as inexpensive, environmentally benign, and reusable catalysts under classical heating conditions and microwave irradiation is reported.
