Cyclopropylation of heterocyclic cores using cyclopropylboronic derivatives

Methods for cyclopropane ring incorporation into various heterocyclic cores using cyclopropylsubstituted organoboron compounds are surveyed. In particular, Suzuki–Miyaura and Chan–Lam reactions, recent coupling processes involving organotrifluoroborates, as well as C–H activation of heterocyclic substrates are discussed.
