Chiral Tetrafluorobenzobarrelene Ligands for the Rhodium‐Catalyzed Asymmetric Cycloisomerization of Oxygen‐ and Nitrogen‐Bridged 1,6‐Enynes

Abstract

N- wie O-Heterocyclen: Die asymmetrische Cycloisomerisierung von Stickstoff- und Sauerstoff-verbrückten 1,6-Eninen wird durch einen kationischen Rhodiumkomplex mit PPh3 und einem chiralen Dien als Liganden katalysiert. Die Umsetzung liefert chirale 3-Aza- und 3-Oxabicyclo[4.1.0]heptene in hohen Ausbeuten und Enantioselektivitäten.
