An enantioselective (4+2) annulation of N-propargylamides and α,β-unsaturated imines/ketones has been accomplished under gold-complex and chiral quinine-derived squaramide synergetic catalysis, providing chiral tetrahydropyridines/dihydropyrans with high efficiency and selectivity. This method complements the (4+2) annulation of allene reagents via a formal cycloaddition on internal π-bond, which is
