Axially chiral compounds widely occur in natural products, biologically active molecules, ligands, and catalysts, their efficient enantioselective synthesis is highly desirable. Herein, we report a novel method for the atroposelective construction of axially N-aryl benzimidazoles with phosphoric acid as organocatalyst via reaction N1-(aryl)benzene-1,2-diamines multicarbonyl compounds. The present provided target products high yields (up to 89%) excellent enantioselectivity 98% ee).
Introduction The nutritional level of the diet plays a crucial role in maintaining balance yak rumen microbiota. To explore relationship between dietary levels, microbiota, and muscle metabolites, we examined characteristics microbiota metabolome under different levels. Methods Randomly divide 24 yaks with similar body weights, [235.96 ± 12.46 kg], into three groups. These groups were subjected to feeding levels: ad libitum (AL), 70% intake (IR70), 40% (IR40). When AL group gained 70 kg...
Supported Pd–Re bi-component catalysts were prepared by an impregnation method and employed in a glycerol hydrogenolysis reaction. The addition of Re into Pd catalyst increased the conversion selectivities to propanediols. characterized N2 adsorption–desorption, XRD, CO chemisorption, TPR NH3-TPD techniques. results showed that changed reduction behaviors components, indicating might have interaction. could increase ability for activation C–O bond further promote activity hydrogenolysis. At...
A novel palladium-catalyzed [4 + 1] cycloaddition to give spirotetrahydrofuran oxindoles has been developed, in which diphenyl 2-oxoindolin-3-yl phosphates were used as the both electrophilic and nucleophilic C1 synthons at C-3 of oxindole unit 2-methylidenetrimethylene carbonate was 1,4-dipole. The cycloannulation performed room temperature provided corresponding good excellent yields. present method affords a new strategy for construction spirooxindole derivatives with unique...
Abstract The ruthenium‐amino structural motif in ruthenacycles and aminomethylpyridine ruthenium complexes turned out to be a useful basis for the design of readily accessible active catalysts racemization alcohols. Inspired by proven ligand acceleration 2‐aminomethylpyridine (ampy) ligands ruthenium‐catalyzed hydrogen transfer, ampy‐based oxazolines 8a 8b were tested led novel catalysts. highly ortho ‐metalated‐ampy Ru complex 7 was demonstrated fast catalyst (100 % 1‐phenylethanol at 70 °C...
Pd–Re/SBA-15 catalysts were prepared by the impregnation method. The influence of interaction between Pd and Re in Pd–Re on glycerol hydrogenolysis was investigated.
Abstract Chiral phosphoric acid‐catalyzed couplings of C ‐alkynyl N,N′ ‐di‐( tert ‐butoxycarbonyl)‐aminals with β ‐naphthols led to chiral propargylamines in moderate high yields excellent enantioselectivity, which the reactions underwent sequential situ formation N ‐( ‐butoxycarbonyl)‐imines ( ‐Boc‐imines) from aminals, and 1,2‐addition ‐Boc‐imines. 1,2‐dihydronaphtho[2,1 ‐b ]furans naphtho[2,1 were prepared satisfactory results when 10 mol% AgOAc 20 2,6‐lutidine or 1.2 equiv....
A phosphine-catalyzed [3+2] annulation between N-phenylpyrazolone derivatives and Morita–Baylis–Hillman carbonates for the synthesis of chiral heterocyclic systems containing spiro[cyclopentane-3,3′-pyrazole] scaffolds has been developed. The reaction afforded desired products in moderate to high yields (up 97%) with good excellent diastereoselectivities 20:1). plausible mechanism also proposed based on previous literature.
Palladium-catalyzed [3 + 3] annulations of 1-alkyl-indolin-2-imines and dialkyl (2-methylenepropane-1,3-diyl) dicarbonates leading to pyrido[2,3- b ]indole derivatives have been developed for the first time.
A sequential [3 + 2]/[2 1] annulation reactions of benzimidazole- and indole-derived acrylonitriles with vinylsulfonium salts have been developed for the first time, shown to provide in yields 32 98% a series azabicyclo[3.1.0]hexanes containing each cyano-substituted tetrasubstituted carbon stereocenter >20 : 1 dr. This method features simplicity, high efficiency broad substrate scopes. Moreover, synthetic utility was demonstrated gram-scale further transformations products.
