A solvent-free S/Co(NO3)2 cascade catalyzed cyclocondensation reaction of aromaticnitriles with 3-amino-1-propanol or 2-aminoethanol has been successfully developed under thermal and microwave conditions. By this two-component protocol, mono- and bis-oxazines and oxazolines were selectively synthesized both in good to excellent yields and short reaction times. This catalytic system exhibits excellent
