A [4 + 3] Annulation Reaction of aza- o-Quinone Methides with Arylcarbohydrazonoyl Chlorides for Synthesis of 2,3-Dihydro-1 H-benzo[ e][1,2,4]triazepines

An unprecedented [4 + 3] annulation reaction of aza-ortho-quinone methides with arylcarbohydrazonoyl chlorides has been achieved under mild conditions. The annulation underwent a sequential conjugate addition/intramolecular annulation/rearrangement, providing a useful method for the synthesis of biologically interesting 2,3-dihydro-1H-benzo[e][1,2,4]triazepine.

Pd(II)-catalyzed enantioselective intramolecular oxidative amination utilizing (+)-camphorsulfonic acid

An enantioselective Pd(II)-catalyzed intramolecular oxidative amination reaction was developed utilizing the commercially available chiral X-type ligand (1S)-(+)-camphorsulfonic acid. The Wacker-type cyclization produced chiral indoline products with enantioselectivies up to 45% ee. Electronic structure calculations employing density functional theory support a trans-aminopalladation mechanism.

Tandem [3 + 2] cycloaddition/1,4-addition reaction of azomethine ylides and aza-o-quinone methides for asymmetric synthesis of imidazolines

An enantioselective synthesis of biologically important imidazolidines has been achieved via a tandem [3 + 2] cycloaddition/1,4-addition reaction of azomethine ylide and aza-o-quinone methides. With the use of this tool, various imidazolidine derivatives are obtained in good yields with excellent diastereoselectivities and enantioselectivities.

Palladium(II)-catalyzed aerobic intramolecular allylic C[sbnd]H activation for the synthesis of indolines

A method for the preparation of indolines via palladium-catalyzed aerobic intramolecular allylic C[sbnd]H activation was developed. Oxygen was successfully used as oxidant with catalytic amount of 1,4-benzoquinone. 16 examples were reported, the majority of substrates gave moderate to good yields.

Synthesis of indoles through highly efficient cascade reactions of sulfur ylides and N-(ortho-chloromethyl)aryl amides

Pd(II)-catalyzed oxidative cyclization reaction for the preparation of 2-substituted 1,2,3,4-tetrahydroquinolines with halide functionality

The first Pd(II)-catalyzed oxidative cyclization reaction was developed for preparation of 2-substituted 1,2,3,4-tetrahydroquinolines from olefinic tosylamides. Under the optimized conditions, up to 86% yield was obtained. This reaction provides direct an

Pd-catalyzed asymmetric aza-Wacker-type cyclization reaction of olefinic tosylamides

The Pd-catalyzed asymmetric aza-Wacker-type cyclization reaction of the olefinic tosylamides with molecular oxygen as the green oxidant was developed. Under the optimized conditions, excellent catalytic activity and good enantioselectivity with up to 74%

Aerobic intramolecular oxidative amination of alkenes catalyzed by NHC-coordinated palladium complexes

Palladium(II) complexes bearing a single N-heterocyclic carbene ligand serve as effective catalysts for the aerobic oxidative cyclization of alkenes with pendant sulfonamides. The use of carboxylic acid cocatalysts (AcOH and PhCO2H) often leads
