Regioselective Pd-Catalyzed Aerobic Aza-Wacker Cyclization for Preparation of Isoindolinones and Isoquinolin-1(2H)-ones
摘要:
A switchable regioselective intramolecular aerobic aza-Wacker cyclization catalyzed by palladium is presented. Isolndollnones or isoquinolin1(2H)-ones could be prepared selectively from the same substrates using different catalysts. The type and steric hindrance of the ligands may be the variables most significant for regiocontrol.
Various C–C and C‐X bonds could be formed by doublefunctionalization of olefins featuring Cu‐mediated assistedtandemcatalysis. Furthermore, one‐pot indoline syntheses with o‐bromostyrenes as an application could be achieved.

The enantioselective, vicinal diamination of alkenes represents one of the stereocontrolled additions that remains an outstanding challenge in organic synthesis. A general solution to this problem would enable the efficient and selective preparation of widely useful, enantioenriched diamines for applications in medicinal chemistry and catalysis. In this article, we describe the first enantioselective

We disclose a nickel/Brønsted acid-catalyzed tandem process consisting of double bond isomerization of allyl ethers and amines and subsequent intramolecular reaction with nucleophiles. The process is accomplished by [(Me3P)4NiH]N(SO2CF3)2 in the presence of triflic acid. The methodology provides rapid access to tetrahydropyran-fused indoles and other oxacyclic scaffolds under very low catalyst loadings
