摘要: The carbozincation of cyclopropene and cleavage cyclopropylzinc generates carbanion intermediates, which in turn can generate oligomeric complexes situ through successive reactions. present reaction controls the sequence C–C bond to give densely functionalized sterically congested alkylamines a single operation. A subtle difference substituent at C=N induced chemoselective cyclopropene.
