Author is Melhado, Asa D.; Luparia, Marco; Toste, F. Dean.
The catalytic enantioselective 1,3-dipolar cycloaddition of munchnone dipoles with electron-deficient alkenes is described. The reaction is catalyzed by chiral bis(phosphine)gold(I) benzoate complexes and provides Δ1-pyrrolines, e.g., I, with excellent regio-, diastereo-, and enantioselectivity. The reaction is proposed to proceed through a 1,3-dipole generated by deprotonation of a gold(I)-activated azlactone.
