Benzoxazines bearing a C4-quaternary stereocenter were accomplished via the rhodium-catalyzed electrophilic trapping of zwitterionic intermediates by isatins and imines, resp. The key intermediates of the strategy are proposed to generate from the reaction of donor-acceptor rhodium carbenes with secondary amides. Usage of chiral BINOL-phosphoric acid co-catalyst resulted in enrichment of enantioselectivity in the trapping process with imines.

Marchetti, Mauro published the artcileAqueous biphasic hydrogenations catalyzed by rhodium and iridium complexes modified with human serum albumin, SDS of cas: 1205-17-0, the main research area is biphasic hydrogenations catalysis rhodium iridium complex; catalyst human serum albumin unsaturated aldehyde.

Water soluble complexes derived from the interaction between Rh(CO)2(acac) and [Ir(COD)Cl]2, resp., with human serum albumin (HSA), were employed in the aqueous biphasic hydrogenation of α,β-unsaturated compounds as 2-cyclohexen-1-one (I), 2-butenal (V), 3-phenyl-2-propenal (IX) and 3-aryl-2-methyl-2-propenals (XIII and XVII). Both catalytic systems Rh/HSA and Ir/HSA showed to be very active in the hydrogenation of ketone I even at low temperature and hydrogen pressure; in particular, the rhodium based catalyst showed to be very selective affording exclusively cyclohexanone (II). The α,β-unsaturated aldehydes investigated required higher temperature (up to 60°) and pressure (5 MPa) to obtain good conversions. In this case Rh/HSA resulted to be more active than Ir based catalyst. In all cases both Rh/HSA and Ir/HSA were easily recycled without significant loss of activity.

Ruiz-Moyano, Santiago published the artcileSelection and application of antifungal VOCs-producing yeasts as biocontrol agents of grey mould in fruits, Related Products of isoquinoline, the main research area is antifungal volatile compound yeast gray mold fruit; Antifungal volatile compounds; Botrytis cinerea; Cherry; Postharvest; Strawberry.

Rotting caused by gray mold (Botrytis cinerea) is a concerning disease for numerous crops both pre- and postharvest stages. Application of antagonistic yeasts is a promising strategy for controlling gray mold incidence which could mitigate undesirable consequences of using synthetic fungicides. In this work, a screening for detection of yeasts isolated from figs producers of antifungal volatile organic compounds (VOCs) were performed by confrontation in double dishes systems. Eleven out of 34 yeasts confronted reduced B. cinerea growth parameter in vitro. This reduction was correlated (p ≤ 0.050) with the production of 10 volatile compounds: two acids (acetic acid and octanoic acid), 7 esters (Et propionate, n-Pr acetate, Iso-Bu acetate, 2-methylbutyl acetate, furfuryl acetate, phenylmethyl acetate, 2-phenylethyl acetate) and one ketone (Heptan-2-one). In bases on in vitro assay, Hanseniaspora uvarum 793 was applied to in vivo assays with strawberries and cherries. The reduction of incidence of B. cinerea in strawberries at 7°C and 25°C was 54.9 and 72.1% after 6 and 3 days, resp. The reduction of incidence of B. cinerea in cherries at 7°C and 25°C was 48.9 and 45.6% after 5 and 4 days, resp. These results showed that VOCs produced by Hanseniaspora uvarum 793 are effective in the control of incidence of Botrytis cinerea in fruits, being a potential alternative to chem. fungicide.

Li, Mao-Lin published the artcileHighly enantioselective carbene insertion into N-H bonds of aliphatic amines, HPLC of Formula: 104-01-8, the main research area is diazo ester amine aliphatic copper aminothiourea chiral carbene insertion; amino acid ester stereoselective preparation.

Aliphatic amines strongly coordinate, and therefore easily inhibit, the activity of transition-metal catalysts, posing a marked challenge to nitrogen-hydrogen (N-H) insertion reactions. We report highly enantioselective carbene insertion into N-H bonds of aliphatic amines using two catalysts in tandem: an achiral copper complex and chiral amino-thiourea. Coordination by a homoscorpionate ligand protects the copper center that activates the carbene precursor. The chiral amino-thiourea catalyst then promotes enantioselective proton transfer to generate the stereocenter of the insertion product. This reaction couples a wide variety of diazo esters and amines to produce chiral a-alkyl a-amino acid derivatives

Sarki, Naina published the artcileSimple RuCl3-catalyzed N-Methylation of Amines and Transfer Hydrogenation of Nitroarenes using Methanol, Computed Properties of 5961-59-1, the main research area is amine preparation methylation; nitroarene transfer hydrogenation RuCl3 catalyst.

Methanol is a potential hydrogen source and C1 synthon, which finds interesting applications in both chem. synthesis and energy technologies. The effective utilization of this simple alc. in organic synthesis is of central importance and attracts scientific interest. Herein, a clean and cost-competitive method with the use of methanol as both C1 synthon and H2 source for selective N-methylation of amines by employing relatively cheap RuCl3.xH2O as a ligand-free catalyst. This readily available catalyst tolerates various amines comprising electron-deficient and electron-donating groups and allows them to transform into corresponding N-methylated products in moderate to excellent yields. In addition, few marketed pharmaceutical agents (e.g., venlafaxine and imipramine) were also successfully synthesized via late-stage functionalization from readily available feedstock chems., highlighting synthetic value of this advanced N-methylation reaction. Using this platform, also attempted tandem reactions with selected nitroarenes to convert them into corresponding N-methylated amines using MeOH under H2-free conditions including transfer hydrogenation of nitroarenes-to-anilines and prepared drug mols. (e.g., benzocaine and butamben) as well as key pharmaceutical intermediates. Further enable one-shot selective and green syntheses of 1-methylbenzimidazole using ortho-phenylenediamine (OPDA) and methanol as coupling partners.

Jamil, A. R. Md. published the artcileN-Methylation of amines and nitroarenes with methanol using heterogeneous platinum catalysts, HPLC of Formula: 5961-59-1, the main research area is amine nitroarene methylation methanol heterogeneous platinum catalysis.

Herein the selective N-methylation of amines and nitroarenes with methanol under basic conditions using carbon-supported Pt nanoparticles (Pt/C) as a heterogeneous catalyst was reported. This method is widely applicable to four types of N-methylation reactions: (1) N,N-dimethylation of aliphatic amines under N2, (2) N-monomethylation of aliphatic amines under 40 bar H2, (3) N-monomethylation of aromatic amines under N2, and (4) tandem synthesis of N-Me anilines from nitroarenes and methanol under 2 bar H2. All these reactions under the same catalytic system showed high yields of the corresponding methylamines for a wide range of substrates, high turnover number (TON), and good catalyst reusability. Mechanistic studies suggested that the reaction proceeded via a borrowing hydrogen methodol. Kinetic results combined with d. functional theory (DFT) calculations revealed that the high performance of Pt/C was ascribed to the moderate metal-hydrogen bond strength of Pt.
