  [Co(P1)] is an effective catalyst for asymmetric cyclopropanation   with  succinimidyl diazoacetate. The Co(II)-catalyzed   reaction is suitable for  various olefins, providing the   desired cyclopropane succinimidyl esters  in high yields and   excellent diastereo- and enantioselectivity. The  resulting   enantioenriched cyclopropane succinimidyl esters can serve   as  convenient synthons for the general synthesis of   optically active  cyclopropyl carboxamides.
