The Rational Design and Synthesis of Water-Soluble Thiourea Ligands for Recoverable Pd-Catalyzed Aerobic Aqueous Suzuki-Miyaura Reactions at Room Temperature

Eight precatalysts containing carboxylic-functionalized thiourea ligands are prepared and their activities and recyclability are evaluated in aerobic aqueous Suzuki-Miyaura reactions. A bulky monothiourea-Pd complex, functionalized with four carboxylic groups, shows the best activity and recyclability in the coupling of aryl bromides with arylboronic acids. The catalyst can be reused at least five times without any significant reduction in its catalytic activity. TEM analysis and the confirmed catalytic activity of the observed black precipitate reveal that Pd nanoparticles are formed during the reactions and are stabilized by the carboxylic-functionalized thiourea ligands.

Synthesis and cytotoxicity of thieno[2,3-b]quinoline-2-carboxamide and cycloalkyl[b]thieno[3,2-e]pyridine-2-carboxamide derivatives

Seventy nine derivatives of thieno[2,3-b]quinolines, tetrahydrothieno[2,3-b]quinoline, dihydrocyclopenta[b]thieno[3,2-e]pyridine, cyclohepta[b]thieno[3,2-e]pyridine and hexahydrocycloocta[b]thieno[3,2-e]pyridine were either synthesized or obtained commercially and tested for their antiproliferative activity against HCT116, MDA-MB-468 and MDA-MB-231 human cancer cell lines. The most potent eight compounds were active against all cell lines with IC50 values in the 80–250 nM range. In general hexahydrocycloocta[b]thieno[3,2-e]pyridines were most active with increasing activity observed as larger cycloalkyl rings were fused to the pyridine ring.

Synthesis of amido-N-imidazolium salts and their applications as ligands in suzuki-miyaura reactions: Coupling of hetero- aromatic halides and the synthesis of milrinone and irbesartan

A new catalytic system based on palladium-amido-N-heterocyclic carbenes for Suzuki-Miyaura coupling reactions of heteroaryl bromides is described. A variety of sterically bulky, amido-N-imidazolium salts were synthesized in high yields from the corresponding anilines. This catalytic system effectively promoted Suzuki-Miyaura couplings of heteroaryl bromides and chlorides with a range of boronic acids to give the corresponding aryl compounds in high yield. The yield was increased with increasing steric bulkiness of the substituted group. Especially, 1-(2,6-diisopropylphenyl)-3-N-(2,4,6-tri-tert- butylphenylacetamido)imidazolium bromide (4bc) exhibited 850,000 TON in the coupling reaction of 2-bromopyridine and phenylboronic acid. In addition, pharmaceutical compounds such as milrinone and irbesartan were synthesized via Suzuki-Miyaura coupling using sterically bulky, amido-N-imidazolium salt (4bc) as a ligand. Copyright

Design of chiral hydroxyalkyl- and hydroxyarylazolinium salts as new chelating diaminocarbene ligand precursors devoted to asymmetric copper-catalyzed conjugate addition

The design and the synthesis of a set of new chiral hy- droxyalkyl- and hydroxyaryl-chelating diaminocarbene ligands is reported. Comparative catalytic studies show the importance of the scaffold design around the NHC unit to obtain a high enantiocontrol in Cu-catalyzed asymmetric conjugate addition (ACA). Whereas low selectivities are observed when the stereogenic centre is placed within the N-heterocyclic ring, an interesting match effect can be observed when central chirality is located within both of the two side chains, which enables up to 92 % ee in the catalysis reaction.
