Combined oxypalladation/C-H functionalization: palladium(II)-catalyzed intramolecular oxidative oxyarylation of hydroxyalkenes.
Originating from the classic Wacker process,1 the palladium(II)-catalyzed oxidative difunctionalization of alkenes has emerged as an attractive strategy for the rapid generation of molecular complexity due to its ability to form multiple carbon–carbon/carbon– heteroatom bonds and stereogenic centers in a single step.2,3,4 This versatility, combined with the broad functional group compatibility ...
متن کاملCyclization-carbonylation-cyclization coupling reaction of propargyl ureas with palladium(II)-bisoxazoline catalyst.
The cyclization-carbonylation-cyclization coupling reaction (CCC-coupling reaction) of propargyl ureas catalyzed by Pd(II)(box) complexes afforded symmetrical ketones bearing two 2-amino-2-oxazoline groups in good to moderate yields.
متن کاملSynthesis of 2,3-disubstituted indole using palladium(II)-catalyzed cyclization with alkenylation reaction.
The reaction of ethyl 2-ethynylphenylcarbamate derivative with alkenes in the presence of a palladium(II) catalyst, copper dichloride and tetrabutylammonium fluoride (TBAF) produced 2-substituted 3-ethenylindoles during refluxing. The intramolecular cyclization reaction of ethyl 2-ethynylphenylcarbamates, which have an ethenyl part in the ethynyl group, was also used to produce carbazole deriva...
متن کاملPalladium-catalyzed [3 + 2] intramolecular cycloaddition of alk-5-enylidenecyclopropanes.
Readily accessible alk-5-enylidenecyclopropanes undergo [3 + 2] intramolecular cycloaddition reactions upon treatment with appropriate palladium complexes. The method allows the rapid and efficient assembly of a variety of bicyclo[3.3.0]octane systems with up to three stereocenters. Preliminary theoretical calculations uncovered previously unsuspected mechanistic possibilities based on either a...
متن کاملPalladium-Catalyzed Fluoroalkylative Cyclization of Olefins.
A palladium-catalyzed fluoroalkylative cyclization of olefins with readily available Rf-I reagents to afford the corresponding fluoroalkylated 2,3-dihydrobenzofuran and indolin derivatives with moderate to excellent yields is reported. This novel procedure provides an efficient method for the construction of Csp3-CF2 and C-O/N bonds in one step. A wide range of functional groups are tolerated. ...
