Citrate trisulfonic acid: A heterogeneous organocatalyst for the synthesis of highly substituted Imidazoles

Citrate trisulfonic acid (CTSA), as a novel recyclable and eco-benign organocatalyst, was employed for the efficient and one-pot synthesis of trisubstituted imidazoles and tetrasubstituted imidazoles using aldehydes, ammonium acetate or aniline, and benzoin, benzyl, or 9,10-phenanthrenequinone under solvent-free conditions providing high to excellent yields. CTSA is easily prepared via the reaction of trisodium citrate and chlorosulfonic acid in high purity. Compared to the conventional procedures, the present method offers several advantages, including high yields, easy work-up, short reaction time, reusability of the catalyst, and simple purification of the products.

Urea-Zinc Chloride Eutectic Mixture-Mediated One-Pot Synthesis of Imidazoles: Efficient and Ecofriendly Access to Trifenagrel

The low-melting mixture urea-ZnCl 2 was evaluated as a novel reaction medium for the synthesis of imidazoles. The reaction between a dicarbonyl compound, ammonium acetate, and an aromatic aldehyde is efficiently catalyzed by the eutectic solvent, yielding a wide variety of triaryl-1 H -imidazoles or 2-aryl-1 H -phenanthro[9,10- d ]imidazoles in good to excellent yields. In addition, the eutectic solvent was reused in five cycles without loss of its catalytic activity. This protocol was further explored for the synthesis of the drug trifenagrel, giving an excellent yield.

The invention discloses a method for preparing a 2-aryl-1H-phenanthro (9,10-d) imidazole derivative in a catalyzed mode, and belongs to the technical field of ionic liquid catalysis. In a preparation reaction, the molar ratio of 9,10-phenanthrenequinone to aromatic aldehyde to ammonium acetate is 1:1:3-5, the molar weight of a non-imidazolyl acidic ionic liquid catalyst accounts for 4-6% that of 9,10-phenanthrenequinone, the volume dose of reaction solvent water in units of milliliter is 5-8 times the molar weight of 9,10-phenanthrenequinone in units of millimole, the time for a reflux reaction is 14-30 min, diethyl ether is used for extraction after the reaction is finished, anhydrous magnesium sulfate is added into extract liquor for drying, suction filtration is carried out, and after rotary evaporation concentration is carried out, filtrate is recrystallized with ethyl acetate to obtain the 2-aryl-1H-phenanthro (9,10-d) imidazole derivative. The method has the advantages that the catalyst is good in biodegradability and high in raw material use ratio, the whole preparation process is easy and convenient to operate and the like, and the method can be industrially applied on a large scale conveniently.

Optimizing electron transfer mediators based on arylimidazoles by ring fusion: Synthesis, electrochemistry, and computational analysis of 2-aryl-1-methylphenanthro[9,10-d ]imidazoles

A significant improvement of the properties of redox catalysts based on the triarylimidazole framework can be achieved with a simple structural modification. By linking the ortho-carbons of the aromatics positioned at C-4 and C-5, a fused framework is generated, removing the distortion from planarity and enhancing the influence of the substituents on the redox properties. This modification leads not only to a much broader range of available redox potentials for the resulting phenanthro[9,10-d]imidazoles but also to improved stability of the corresponding radical cation. These concepts were verified with eight new phenanthro[9,10-d]imidazole derivatives, using cyclic voltammetry and DFT calculations. For this purpose, an optimized and general synthetic route to the desired compounds was developed. An excellent linear correlation of the calculated effective ionization potentials with the experimental oxidation potentials was obtained, allowing for an accurate prediction of oxidation potentials of derivatives yet to be synthesized. Moreover, high catalytic activity was found for electro-oxidative C-H activation reactions.
