Abstract: Herein, Pd‐catalyzed asymmetric [3 + 2] cycloaddition and olefin isomerization is reported to afford chiral 3‐pyrrolines using cyano‐TMM (trimethylenemethane) and cyclic sulfamidate imines. This represents a unique protocol to provide chiral N‐heterocycles bearing endocyclic olefins… read more here.
