Table 1. Effect of the porphyrin ligand on the stereoselective metalloradical C–H alkylation of α-methoxycarbonyl-α-diazosulfone 1a catalyzed by [Co(D ₂-Por*)] ^a .

^aReactions were carried out at room temperature for 72 h in a one-time fashion without slow addition of the diazo reagent using [Co(Por)] under N₂.

^bIsolated yields.

^cThe trans : cis diastereomeric ratio determined by ¹H-NMR.

^dEnantiomeric excess determined by chiral HPLC.

^eNo reaction.

^fFor clarity, the other two meso-groups of the porphyrin are omitted.
