tertiary amine derivatives have been prepared by a one-pot three-component Petasisborono–Mannichreaction of two different salicylaldehydes and 2-formylpyridine, substituted morpholine/piperidines and aryl boronic acids. These reactions were carried out under microwave irradiation using a catalytic amount of La(OTf)3 in a short reaction time. This procedure has the advantages of high conversions with excellent
