dc.description.abstract | Enantioselective [2+2] cycloaddition of C(1)-ammonium enolates generated catalytically using the isothiourea HyperBTM with N alkyl isatins gives spirocyclic β-lactones. In situ ring-opening with an amine nucleophile generates isolable highly enantioenriched products in up to 92:8 dr and in >99:1 er. | |
