A method has been developed for the chemo- and stereoselective Suzuki-Miyaura cross-coupling of optically enriched gem-diboronyl compounds with various aryl bromides. Experimental evidence suggests that the Lewis acidity of the second boron group in these substrates plays a significant role in facilitating these otherwise challenging cross-coupling processes. beta-Diboronyl esters may be successfully cross-coupled in excellent yield and enantiomeric excess with prior conversion of the pinacol boronate to the corresponding trifluoroborate salt. In contrast, a substrate bearing a Weinreb amide can undergo direct coupling of the Bpin moiety, likely due to the stronger coordination of the more basic amide carbonyl group. The resulting optically enriched secondary boronate may be used in a second enantioselective cross-coupling to afford pharmaceutically relevant diarylmethane products. The use of a Weinreb amide substrate allows for facile postcoupling modification, as demonstrated by a transformation to the corresponding ketone.

Application of 52409-22-0, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 52409-22-0, Name is Pd2(DBA)3, molecular formula is C51H42O3Pd2.

Palladium-catalyzed allylic C?H oxidation has been widely studied, but most precedents use acetic acid as the coupling partner. In this study, a method compatible with diverse carboxylic acid partners has been developed. Use of a Pd0 precatalyst under aerobic reaction conditions leads to oxidation of Pd0 by O2 in the presence of the desired carboxylic acid to generate a PdII dicarboxylate that promotes acyloxylation of the allylic C?H bond. Good-to-excellent yields are obtained with a roughly 1:1 ratio of the alkene and carboxylic acid reagents. Optimized reaction conditions employ 4,5-diazafluoren-9-one (DAF) as a ligand, in combination with a quinone/iron phthalocyanine cocatalyst system to support aerobic catalytic turnover.

Trifluoroacetimidoyl metal complexes are useful intermediates for the selective synthesis of organofluorine compounds. Herein, we report preparations, structures, and reactions of fluorinated imidoyl palladium complexes. Oxidative addition of trifluoroacetimidoyl halides to Pd(PPh3)4 afforded quantitatively the imidoyl palladium(II) complexes with phosphine ligands. The reaction of trifluoroacetimidoyl iodides with Pd 2(dba)3 provided the phosphine-free imidoyl palladium complex in high yields. The X-ray crystal structure analysis of the phosphine-free complex [Pd(mu-I){mu-C(CF3)=N(PMP)}]4 revealed a cyclic tetranuclear structure containing the imidoyl and iodo bridges. The generation of aminotrifluoromethylcarbene equivalents by protonation or electrophilic alkylation of imidoyl palladium(II) complexes is discussed.

A collection of fourteen diphenylamine macrocyclic derivatives containing a peptide chain with different substituents was synthesized using a protocol of two Ugi four component reactions (Ugi-4CR) and a Buchwald-Hartwig macrocyclization. Their anti-inflammatory effects were assayed with an ear edema model using 12-O-tetradecanoylphorbol-13-acetate, while the activity of myeloperoxidase was determined to evaluate the index of leukocyte infiltration. Compound 5e had an ID50 of 0.18 muM per ear with a potency higher than that of the reference drugs indomethacin and celecoxib (0.24 and 0.91 muM per ear, respectively). Moreover, the cytotoxicity of the macrocycles was determined in two healthy cell lines, showing a low percentage of toxicity.
