Trideuteriomethoxylation of aryl and heteroaryl halides

Direct access to trideuteriomethoxylated aromatic and heteroaromatic compounds has been developed. Various aryl and heteroaryl halides underwent d3-methoxylation under mild reaction conditions by using a catalyst system composed of the commercially available monodentate phosphane ligand tBuXPhos and Pd(OAc)2. Inexpensive CD3OD served as an efficient trideuteriomethoxylating agent. The simple and straightforward synthesis of labeled methyl (hetero)aryl ethers via palladium-catalyzed C-O cross-coupling reaction of (hetero)aryl halides with CD3OD was developed. The tBuXPhos ligand is used for the first time in ether synthesis. Copyright

An improved diphosphine-iridium (I) catalyst system for the asymmetric hydrogenation of cyclic imines: Phthalimide as an efficient co-catalyst

The asymmetric hydrogenation of cyclic ketimines, 1-alkyl-3,4-dihydroisoquinolines 5a,b was carried out with diphosphine-iridium(I) complex catalysts in the presence of various imides or amides as a co-catalyst. Remarkable effects of five-membered imides on the enantioselectivity and the catalytic activity were observed. The enantioselectivity with a BCPM 1-iridium(I) complex was much improved up to 93% ee by addition of phthalimide.

Palladium-catalysed amination of halopyridines on a KF-alumina surface

Palladium-catalysed C-N hetero cross-coupling reactions between bromopyridines and amines (both primary and secondary) can be efficiently performed on a KF-alumina (basic) surface, thus negating the use of strong bases such as sodium tert-butoxide. The reaction conditions are optimised with reference to catalytic systems, solvents and the surface.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 4-Bromoisoquinoline, you can also check out more blogs about1532-97-4

An efficient protocol for the synthesis of monofluoroalkylated (hetero)arenes via Pd-catalyzed alpha-(hetero)arylation of alpha-fluoroketones with (hetero)aryl bromides

An efficient synthesis of monofluoroalkylated N-heteroarenes using alpha-fluoroketones as monofluoroalkyl reagents was developed. A variety of novel alpha-(hetero)aryl-alpha-fluoroketones and monofluoroalkylated N-heteroarenes were obtained in moderate to good yields. Notable advantages of this protocol include a low catalyst loading, easily prepared monofluoroalkyl reagents and wide substrate scope.

ANGULARLY ALKYLATED 8-AZA-D-HOMOGONANES

We have established that cyclic azomethines (1-alkyl-substituted 3,4-dihydroisoquinolines) enter into the annelation reaction with cyclic beta-triketones (2-acyl-1,3-cyclohexanediones) with formation of C-9 angularly alkylated 8-aza-D-homogonanes.We have shown that the reaction of asymmetric beta-triketones (2-acetyl-5,5-dimethyl-4-methoxycarbonyl-1,3-cyclohexanedione) is accomplished regioselectively, leading to the 17-methoxycarbonylated 8-aza-D-homogonane derivative, existing in solutions in the form of a mixture of stereoisomers with respect to C-17 (due to keto-enol ta utomerism) and in crystals in the form of a single stereoisomer.The structure of the 8-azo-D-homogonanes has been proven by UV, IR, and PMR spectra.

Ru(II) complexes of N-Alkylated TsDPEN ligands in asymmetric transfer hydrogenation of ketones and imines

N-Alkylated TsDPEN derivatives bearing a small alkyl group act as highly efficient ligands in Ru(II) complexes for the asymmetric transfer hydrogenation of imines and ketones. A larger alkyl group serves to significantly reduce the activity of the catalyst; however, high enantiomeric excesses are still obtained. An X-ray crystal structure of the N-benzyl derivative reveals a conformation that permits hydrogen transfer through a six-membered transition state. A transition state structure for the imine reduction process is proposed.

Palladium-catalyzed selective decarboxylative coupling reaction versus direct C – H arylation for arylation of heteroaromatics

Conditions for selective palladium-catalyzed decarboxylative 2-arylation of 3-substituted thiophene and furan derivatives bearing an ester at C2 position have been established. By using 2 mol% phosphine-free Pd(OAc)2 as the catalyst and a mixture of KOH and K2CO3 as the bases, in dimethylacetamide, moderate to good yields of the desired 2-arylated products were obtained. A range of functional groups such as nitrile, nitro, formyl or acetyl on the aryl bromides was tolerated. This method allows us to employ in some cases more convenient reactants in terms of cost or physical properties (boiling point) for arylations. Copyright
