Synthesis of 2,3-disubstituted indole using palladium(II)-catalyzed cyclization with alkenylation reaction.

چکیده
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 derivatives.

Palladium-catalyzed highly regioselective 6-exo-dig cyclization and alkenylation of ortho-ethynylanilides: the synthesis of polyene-substituted benzo[d][1,3]oxazines.
A Pd-catalyzed highly regioselective 6-exo-dig cyclization/alkenylation reaction of ortho-ethynylanilides has been developed. This tandem cross-coupling protocol represents a simple, efficient, step- and atom-economic approach for the construction of scarcely known polyene-substituted benzo[d][1,3]oxazines in moderate to excellent yields with a broad substrate scope.

A base-controlled synthesis of 2-substituted secondary and tertiary 1H-indole-3-carboxamides through PdCl(2)-catalyzed cyclization of o-alkynyltrifluoroacetanilides followed by isocyanide insertion has been developed. The reaction proceeds smoothly at ambient temperature using O(2) in air as the sole oxidant of the palladium catalyst.

A copper-catalyzed synthesis of 2-(aminomethyl)indole through domino three-component coupling-cyclization has been developed. This reaction proceeds through Mannich-type coupling of 2-ethynylanilines, aldehydes, and secondary amines, followed by hydroamination. This indole formation was applicable to the synthesis of 4-methylene-2,3,4,9-tetrahyro-1H-pyrido[3,4-b]indoles and 5,6,7,8-tetrahydrobe...

A one-pot indole synthesis consisting of a highly regioselective TiCl(4)-catalyzed hydroamination and a 5-endo Heck cyclization starting from 2-chloroaniline is described, using an in-situ generated, sterically hindered imidazol-2-ylidene palladium complex.
متن کاملTandem addition-cyclization reactions of 2-alkynylbenzenamines with isocyanates catalyzed by PdCl2.
Tandem addition-cyclization reactions of 2-alkynylbenzenamines with isocyanates catalyzed by palladium chloride are described. This reaction is performed in the presence of 10 mol% of palladium chloride in THF at 80 degrees C, which provides an efficient and practical route for the synthesis of 1,2-disubstituted indoles.
