Part A: Palladium(II)-Catalyzed Enantioselective Saucy-Marbet Claisen Rearrangement of Propargyloxy indoles to Quaternary Oxindoles and Spirocyclic Lactones. Part B: The Regioselective Oxidative Coupling of Phenols . [PDF]

, 2013
Part A. The first catalytic, enantioselective Saucy-Marbet Claisen rearrangement has been developed. Palladium(II) catalysts with BINAP or t-BuPHOX ligands were discovered as superior in catalyzing Claisen rearrangements of proparyloxy-substituted ...
