Preparation of 3‑Aryl-2-aminoindoles via Rhodium-Catalyzed Coupling Reaction between 2‑Arylpyridines and 3‑Diazoindolin-2-imines

open access: yes, 2016
Rhodium-catalyzed coupling reaction of 3-diazo­indolin-2-imines with 2-aryl­pyridines, 2-phenyl­pyrimidines, or 1-phenyl­pyrazoles furnished the corresponding 3-aryl-2-amino­indoles in moderate to excellent yields.

An (R)‐Imine Reductase Biocatalyst for the Asymmetric Reduction of Cyclic Imines [PDF]

open access: yesChemCatChem, 2015
AbstractAlthough the range of biocatalysts available for the synthesis of enantiomerically pure chiral amines continues to expand, few existing methods provide access to secondary amines. To address this shortcoming, we have over‐expressed the gene for an (R)‐imine reductase [(R)‐IRED] from Streptomyces sp.

Stereoselective Reduction of Imines with Trichlorosilane Using Solid-Supported Chiral Picolinamides

open access: yesMolecules, 2016
The stereoselective reduction of imines with trichlorosilane catalyzed by chiral Lewis bases is a well-established procedure for the synthesis of enantio-enriched amines.

Old Dogs with New Tricks: Antiparasitic Potential of Structurally Diverse 5-Nitrofuran and 5-Nitrothiophene Imines and Acyl Hydrazones

open access: yesScientia Pharmaceutica, 2023
Miscellaneous imines and acyl hydrazones were prepared from 5-nitrofuraldehyde and 5-nitrothiophene-2-carboxaldehyde. Their activities against Toxoplasma gondii and Leishmania major parasites were evaluated.

No Transition Metals Required – Oxygen Promoted Synthesis of Imines from Primary Alcohols and Amines under Ambient Conditions

open access: yes, 2022
The synthesis of imines denotes a cornerstone in organic chemistry. The use of alcohols as renewable substituents for carbonyl-functionality represents an attractive opportunity. Consequently, carbonyl moieties can be in situ generated from alcohols upon

Determination of Ka values for some phenolic compounds derived from benzoyl acetonitril by electrical conductivity [PDF]

open access: yesمجلة التربية والعلم, 2013
This investigation was started by synthesis of three phenolic Schiff bases from the mother compound benzoyl acetonitril, These having OH groups in o، m، p positions on amino side of molecules. The structures of these imines were confirmed from U.V. and I.

Unprecedented selective synthesis of imines by photo-oxidative coupling under N2O atmosphere

open access: yes, 2023
The synthesis of imines was unprecedently performed using nitrous oxide (N2O) as a highly selective oxidative agent for the photocatalytic homo-coupling of amines. In a similar way, unsymmetrical imines were produced through cross-coupling of amines with

Periselectivity in the Aza-Diels–Alder Reaction of 1-Azadienes with α-Oxoketenes: A Combined Experimental and Theoretical Study

open access: yesMolecules, 2020
Inversions in the periselectivity of formal aza-Diels–Alder cycloadditions between α-oxoketenes generated by a thermally-induced Wolff rearrangement and 1-azadienes were observed experimentally as a function of the α-oxoketene and the 1-azadiene, as well
