title: Solvent-free microwave-assisted multi-component reaction for preparation of 2-amino-1-aryl-2-(cyclohex-1-enyl)ethanones as precursors of pseudoephedrine analogues.
abstract: Microwave irradiation of chloroacetylarenes and enamines induced an aza-Darzens reaction followed by rearrangement of the aziridinium intermediate to give (2-amino-3-alkenoyl)arenes that were reduced selectively to syn-beta-aminoalcohols as pseudo-ephedrine analogues.
