Intermolecular Heck Coupling with Hindered Alkenes Directed by Potassium Carboxylates

Pd0-catalyzed Mizoroki?Heck reactions traditionally exhibit poor reactivity with polysubstituted, unbiased alkenes. Intermolecular reactions with simple, all-carbon tetrasubstituted alkenes are unprecedented. Herein we report that pendant carboxylic acids, combined with bulky monophospine ligands on palladium, can direct the arylation of tri- and tetrasubstituted olefins. Quaternary carbons are established at high Fsp3 attached-ring junctures and the carboxylate directing group can be removed after coupling. Carboxylate directivity prevents over-arylation of the new, less substituted alkene, which can be diversified in subsequent reactions.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Application In Synthesis of Tris(dibenzylideneacetone)dipalladium-chloroform, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 52522-40-4, in my other articles.

The Diastereoselective Synthesis of Pyrroloindolines by Pd-Catalyzed Dearomative Cycloaddition of 1-Tosyl-2-vinylaziridine to 3-Nitroindoles

An efficient, diastereoselective synthesis of densely functionalized pyrroloindolines is reported. The reaction proceeds via cycloaddition of a vinylaziridine-derived Pd-stabilized 1,3-dipole to electron-deficient 3-nitroindoles. The reactions give the trans diastereoisomer with high selectivity; however, when a 4-substituent is present on the indole ring, a reversal of diastereoselectivity is observed.

Palladium-catalyzed regio-, diastereo-, and enantioselective allylation of nitroalkanes with monosubstituted allylic substrates

Pd-catalyzed asymmetric allylic alkylation of nitroalkanes and monosubstituted allylic substrates was performed to afford products with two adjacent chiral centers and with excellent regio-, diastereo-, and enantioselectivities. The usefulness of the protocol in organic synthesis was demonstrated by transformation of the product to an optically active homoallylamine, a 2,3-disubstituted tetrahydropyridine, and an alpha,beta-disubstituted amino acid derivative.

Csp2-Csp2 and Csp2-N Bond Formation in a One-Pot Reaction between N-Tosylhydrazones and Bromonitrobenzenes: An Unexpected Cyclization to Substituted Indole Derivatives

A novel, sequential, palladium-catalyzed, cross-coupling reaction using N-tosylhydrazone and bromonitrobenzene derivatives followed by reductive cyclization has been developed. This transformation providing an efficient route to unexpected N-arylindole derivatives involves, in a one-pot reaction, the formation of one Csp2-Csp2 bond and two Csp2-N bonds together with the cleavage of one Csp2-heteroatom bond. Evaluation of the biological activity led to the identification of compound 5a, which displays potent activity at nanomolar concentrations against human colon carcinoma cell line.
