For the first time, α-formyldiazoacetates have been successfully applied for the asymmetric cyclopropanation of alkenes <i>via</i> Co(ii)-based metalloradical catalysis. The cobalt(ii) complex of the <i>D</i><sub>2</sub>-symmetric chiral amidoporphyrin [Co(3,5-Di <sup><i>t</i></sup> Bu-ChenPhyrin)] is an effective metalloradical catalyst that can activate α-formyldiazoacetates to cyclopropanate both aromatic and aliphatic olefins with varied electronic properties, affording the synthetically use ...[more]
