Melhado, Asa D. published the artcileAu(I)-catalyzed enantioselective 1,3-dipolar cycloadditions of munchnones with electron-deficient alkenes, Formula: C38H24F4O4P2, the publication is Journal of the American Chemical Society (2007), 129(42), 12638-12639, database is CAplus and MEDLINE.

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.
