Reported is a highly enantioselective copper‐catalyzed Markovnikov protoboration of unactivatedterminalalkenes. A variety of simple and abundant feedstock α‐olefins bearing a diverse array of functional groups and heterocyclic substituents can be used as substrates, and the reaction proceeds under mild reaction conditions at ambient temperature to provide expedient access to enantioenriched alkylboronic
