CO2 hydrogenation to ethanol is of practical importance but poses a significant challenge due the need forming one C-C bond while keeping C-O intact. CuI centers could selectively catalyze CO2-to-ethanol conversion, catalytic sites were unstable under reaction conditions. Here we report use low-intensity light generate species in cavities metal-organic framework (MOF) for ethanol. X-ray photoelectron and transient absorption spectroscopies indicate generation via single-electron transfer...
Abstract Precise chiral recognition was firstly realized in the construction of diastereomeric biaryl monophosphines by means substrate‐directed asymmetric annulation reactions. A series new chiral‐bridged atropisomeric biphenyl monophosphine ligands with tunable dihedral angles accordingly synthesized successfully without a resolution step being needed. Using these ligands, different kinds axially 1,1′‐biaryl‐2‐phosphonates including first reported quinolyl phosphonates were prepared 42–97%...
The one-pot MAC (Masked Acyl Cyanide) reaction is used to perform the tandem oxyhomologation of N,N-dibenzyl-l-phenylalaninal and coupling with nitrogen nucleophiles provide a wide selection amide peptide derivatives (2S,3S)-allophenylnorstatin in generally good yields high anti selectivity, often dr >98:2. procedure works equally well other selected N,N-dibenzyl α-amino aldehydes, achieve very short synthesis (2S,3S,S)-epibestatin.
<bold>L6</bold>–Pd<sub>2</sub>(dba)<sub>3</sub> showed excellent activity in the Suzuki–Miyaura reaction of sterically hindered and electron-rich aryl halides with boronic acids.
Pd-catalyzed asymmetric Suzuki–Miyaura couplings of 3-methyl-2-bromophenylamides, 3-methyl-2-bromo-1-nitrobenzene and 1-naphthaleneboronic acids have been successfully developed the corresponding axially chiral biaryl compounds were obtained in very high yields (up to 99%) with good enantioselectivities 88% ee) under mild conditions. The chiral-bridged biphenyl monophosphine ligands by our group exhibit significant superiority naphthyl counterpart MOP both reactivity enantioselectivity...
The three-component reaction between a protected α-amino aldehyde, an alcohol and α-silyloxymalononitrile provides expedient access to α-hydroxy-β-amino acid derivatives. prototypical process, performed on N-Cbz-phenylalaninal, is known proceed with syn diastereoselectivity. present study demonstrates that the diastereoselectivity of can be inverted, using rationale Felkin-Anh interaction model. Reactions N,N-dibenzyl-L-phenylalaninal high anti diastereoselectivity, providing panel...
Employing salicylic acids and substituted 3-butyn-2-ones as the substrates, a morpholine catalyzed tandem dual Michael addition afforded benzodioxin skeleton.
A Brønsted acid‐catalyzed aza‐Mannich reaction between 3‐hydroxyisoindolin‐1‐ones and N ‐ tert ‐butyl hydrazones was developed. Under the catalysis of racemic phosphoric acid or trifluoroacetic mild conditions, this domino allows for efficient synthesis 3‐(hydrazono)isoindolin‐1‐one derivatives in excellent yields with high chemoselectivities. The E ‐configuration hydrazone products determined by X‐ray single‐crystal diffraction 5w .
By means of the direct condensation N-aminoethylpyrroles and isatins, followed by a chiral phosphoric acid-catalyzed asymmetric intramolecular Friedel-Crafts reaction, new class valuable 3',4'-dihydro-2'H-spiro[indoline-3,1'-pyrrolo[1,2-a]pyrazin]-2-ones bearing quaternary carbon stereocenter were successfully synthesized in good to excellent yields with moderate enantioselectivities under mild reaction conditions.
Abstract A series of new biphenyl N,P‐monophosphine ligands L have been developed by introduction two methoxy groups to the backbone. The were found be much more effective than their counterpart Buchwald in Suzuki–Miyaura coupling reactions sterically hindered and electron‐rich aryl chlorides with boronic acids. variety tri‐ ortho ‐substituted or tetra‐ biaryls hetero‐biaryls conveniently prepared up 99 % yield using L1 ‐[Pd 2 (dba) 3 ] (dba=dibenzylideneacetone) as catalyst.
