Herein an unprecedented cobalt-catalyzed highly site-, diastereo- and enantioselective protocol for stereoselective formation of nucleophilic allyl-Co(II) complexes followed by addition to aldehydes RCHO (R = Ph, 2-furyl, cyclohexyl, etc.) is presented. The reaction features diastereo- and enantioconvergent conversion of easily accessible allylic alc. derivatives, e.g., 2-(3,4-dihydro-1(2H)-naphthalenylidene)ethanol to diversified enantioenriched homoallylic alcs. e.g., I with remarkably broad scope of allyl groups that can be introduced. Mechanistic studies indicated that allyl radical intermediates were involved in this process. These new discoveries establish a new strategy for development of enantioselective transformations through capture of radicals by chiral Co complexes, pushing forward the frontier of Co complexes for enantioselective catalysis.
