Abstract: A three-step process for the enantioselective assembly of cis-fused octahydrophenanthrenes with a quaternary stereocenter is reported. This synthetic strategy relies on a regioselective γ-alkylation, a one-pot sequence of asymmetric hydrogenation and oxidation, and an intramolecular…

Abstract: An intramolecular dearomatizing spirocyclization of indoles by oxidative N-heterocyclic carbene catalysis is reported. C2-iodinated indoles are used as substrates in combination with aroyl azolium ions as acceptors, which provides C2-iodinated indolenines containing an all carbon…

Abstract: A highly enantioselective Cu(II)-catalyzed borylative reaction of β-trifluoromethyl β,β-disubstituted enones was developed, which provide a facile access to a variety of chiral alkylboronic esters with a quaternary stereocenter including both a trifluoromethyl group and a…

Abstract: Herein, we describe an effective strategy for enantioselective synthesis of oxindoles having a C3-quaternary stereocenter via N-heterocyclic carbene (NHC) catalyzed desymmetrization of diols. The process is based on the catalytic asymmetric transfer acylation of primary…
