Abstract
AbstractThe highly chemo‐, enantio‐, and diastereoselective catalyst‐controlled intramolecular allylic C−H insertion and cyclopropanation of donor/donor carbenes are reported. The RuII/Pybox complex selectively catalyzed the intramolecular allylic C−H insertion, providing vinyl‐substituted dihydroindoles with greater than 20:1 chemoselectivity and up to greater than 99 % ee. Chiral dirhodium(II) tetracarboxylates, however, selectively promoted the intramolecular cyclopropanation, giving rise to cyclopropane‐fused tetrahydroquinoline derivatives in excellent yields with greater than 99:1 chemoselectivity and up to 97 % ee.
