Late Stage Functionalization of Secondary Amines via a Cobalt-Catalyzed Electrophilic Amination of Organozinc Reagents

A general preparation of polyfunctional hydroxylamine benzoates from the corresponding secondary amines is reported. This convenient synthesis allows the setup of a late-stage functionalization of various secondary amines, including pharmaceuticals and peptidic derivatives. Thus, a cross-coupling of hydroxylamine benzoates with various alkyl-, aryl-, and heteroaryl-zinc chlorides in the presence of 5 mol % CoCl2 (25 C, 2 h) provides a range of polyfunctional tertiary amines. This method was used to prepare penfluridol and gepirone.

Sustainable HandaPhos-ppm Palladium Technology for Copper-Free Sonogashira Couplings in Water under Mild Conditions

Complexation of ca. 1000 ppm Pd(OAc)2 with the ligand HandaPhos (1-1.5:1) leads to a precatalyst that efficiently mediates Sonogashira couplings in aqueous nanomicelles under very mild conditions. Neither copper nor organic solvent is required in the reaction medium, and the product can be isolated directly from the reaction flask, leaving behind a reaction mixture that can be recycled without additional additives.

Mild negishi cross-coupling reactions catalyzed by acenaphthoimidazolylidene palladium complexes at low catalyst loadings

Considering that the strong sigma-donor property of ylidenes derived from pi-extended imidazolium salts is conducive to increasing the catalytic activity of the resulting palladium N-heterocyclic carbene complexes, robust acenaphthoimidazol-ylidene palladium complexes 3a-c with varying bulky substituted groups were prepared from the corresponding acenaphthoimidazolium chlorides by heating with PdCl2 and K2CO3 in neat 3-chloropyridine in satisfactory yields. Even at a catalyst loading as low as 0.25 mol %, complex 3a exhibited extremely high catalytic activity toward Negishi cross-coupling of alkylzinc reagents with a wide range of (hetero)aryl halides under mild reaction conditions within 30 min. Besides a great number of bromoarenes, various less expensive and inactive (hetero)aryl chlorides were coupled successfully with the alkyl- and arylzinc reagents, in which active functional groups (such as -NH2) were well tolerated even in one-pot dicoupling transformations without protection. In addition, in the case of coupling with secondary alkylzinc reagents, undesired beta-hydride elimination leading to isomerized linear products was efficaciously suppressed. The catalyst system also displayed superiority in the construction of heterobiaryls through the coupling of heteroarylzinc reagents and heterocylic chloroarenes which were hardly accessible from the corresponding organoboron reagents by Suzuki-coupling reactions. Therefore, the protocol described in this paper represents a mild, general, and scalable approach to access various structurally intriguing and functionalized (hetero)aryls.

Synthesis of 5,7,12,14-tetraarylpentacenes from pentacene-5,7,12,14-tetrone and characterisation of the tetrol intermediates

Pentacene has excellent semi-conducting properties but its practical use in organic thin-film transistors (OTFTs) has some drawbacks caused by its sensitivity to oxygen and low solubility. In order to overcome these problems one can introduce substituents on the ring system. In this context, we are investigating the possibility of introduction of aryl substituents on the pentacene backbone. 5,7,12,14-Tetraaryl-substituted pentacenes are described in this article. They have been prepared from the 5,7,12,14-aryl-substituted pentacene-5?,7?,12?,14?-tetrol. We isolated all isomers of the tetrol. We also found that the 5,7,12,14-thienylpentacene-5?, 7?,12?,14?-tetrol can undergo rearrangement to afford both 5,5?,7,7?-tetrathienylpentacene-12,14-one and 5,5?,12, 12?-tetrathienylpentacene-7,14-one.

Palladium-Catalyzed Carbonylative alpha-Arylation of tert -Butyl Cyanoacetate with (Hetero)aryl Bromides

A three-component coupling protocol has been developed for the generation of 3-oxo-3-(hetero)arylpropanenitriles via a carbonylative palladium-catalyzed alpha-arylation of tert-butyl 2-cyanoacetates with (hetero)aryl bromides followed by an acid-mediated decarboxylation step. Through the combination of only a stoichiometric loading of carbon monoxide and mild basic reaction conditions such as MgCl2 and dicyclohexylmethylamine for the deprotonation step, an excellent functional group tolerance was ensured for the methodology. Through the use of 13C-labeled carbon monoxide generated from 13COgen, the corresponding 13C-isotopically labeled beta-ketonitriles were obtained, and these products could subsequently be converted into cyanoalkynes and 3-cyanobenzofurans with site specific 13C-isotope labeling. (Chemical Equation Presented).
