A gold-catalyzedtandemcycloisomerization/oxidation of homopropargyl amides has been developed, which provides ready access to synthetically useful chiral γ-lactams with excellent ee by combining the chiral tert-butylsulfinimine chemistry and gold catalysis. The utility of this methodology has also been demonstrated in the synthesis of biologically active compound S-MPP and natural product (−)-bgugaine
