The formation of alkoxyl boronate complexes in cross-coupling reactions typically undergo classical transmetallation followed by reductive elimination to form C–C and C–X bonds. Here, the authors report an iridium-catalyzed asymmetric alkylation that enables the stereoselective construction of cis-cyclobutanes, employing the high ring strain of bicyclo[1.1.0]butane-derived boronate complexes to induce 1,2-alkoxy migration.
