A family of highly selective allosteric modulators of the metabotropic glutamate receptor subtype 5

We have identified a family of highly selective allosteric modulators of the group I metabotropic glutamate receptor subtype 5 (mGluR5). This family of closely related analogs exerts a spectrum of effects, ranging from positive to negative allosteric modu

C[sbnd]N bond formation in alicyclic and heterocyclic compounds by amine-modified nanoclay

In the current protocol, amine functionalized montmorillonite K10 nanoclay (NH2-MMT) was applied to catalyze the formation of C[sbnd]N bonds in the synthesis of azines and 2-aminothiazoles at room temperature. In comparison with the current methods of C[sbnd]N bond formation, this approach displays specific advantages include atom economy, clean conversion, design for energy efficiency, the use of nontoxic and heterogeneous catalyst, higher purity and yields, safer solvent and reagents for this organic transformation.

Tungsten hexachloride nanoparticles loaded on montmorillonite K-10: a novel solid acid catalyst in the synthesis of symmetrical and unsymmetrical azines

In the present investigation, we have developed a novel technique to prepare azines using nano-WCl6 loaded on Montmorillonite K10 clay as a highly active catalyst. A variety of aldehydes and ketones were efficiently converted to the corresponding azines using catalytic amounts of nanosized WCl6/Mont. K10 under mild conditions. The nanostructures of WCl6 loaded on Mont. K10 as solid acid catalyst have been prepared by solid dispersion method. The advantages of this catalyst are rapid completion of the reactions, simplicity of performance, lack of pollution and mild and green reaction conditions. The morphologies, structure, and chemical components of parent and modified clay were successfully characterized using SEM, FT-IR, CV, XRD and EDX measurements.

An expeditious synthetic approach towards the synthesis of Bis-Schiff bases (aldazines) using ultrasound

Aldazines (Bis-Schiff bases) 1-24 were synthesized using aromatic aldehydes (heterocyclic and benzaldehydes) and hydrazine hydrate under reflux using conventional heating and/or via ultrasound irradiation using BiCl3 as catalyst. Ultrasonication conditions with cat. BiCl3 proved to be an effective, environmentally friendly synthetic procedure. This methodology is robust in the presence of electron donating and electron withdrawing groups affording desired products with high yields (>95%) in just a couple of minutes vs. hours using conventional heating.

Monohydrocyanation of symmetrical azines using potassium hexacyanoferrate(II) as an environmentally friendly cyanide source

The monohydrocyanation of symmetrical azines to synthesize α-hydrazinonitriles using potassium hexacyanoferrate(II) as cyanide source and benzoyl chloride as a promoter under catalyst-free conditions is described. The advantages of this protocol are the environmentally friendly cyanide source, high yield, and simple work-up procedure. Georg Thieme Verlag Stuttgart New York.

Synthesis of 1H-indazole: A combination of experimental and theoretical studies

A new practical synthesis of 1H-indazole is presented. A previous mechanism for the cyclization step is proved to be nonfeasible and a hydrogen bond propelled mechanism is proposed. The new mechanism is suitable for similar cyclization, and a new reaction is predicted. Springer Science+Business Media B.V. 2012.

Orthoamide, LX [1]. N,N,N',N'-Tetraformylhydrazine- a Formylation Agent for Aromatic Compounds of Wide Scope

The reagent system formed from N,N,N',N'-tetraformylhydrazine (3) and aluminum chloride allows the formylation of aromatic compounds. The scope of the method is comparable with the Olah formylation and the Gross-Rieche procedure, since benzene and fluorobenzene can be formylated. Two formyl groups are transferred from 3 to the aromatic nuclei when a molar ratio 4:1:4 (aluminum chloride/3/aromatic compound) is chosen.

A novel approach to fluoro-containing alkenes

A new and general one-pot transformation of aromatic aldehydes to fluorinated olefins containing -CH=C(Cl)CF3 or -CH=C(F)CClF2 moieties is described. Freons CCl3CF3 and CCl2FCClF2 were used as trifluoromethyl and difluoromethyl C2-building blocks respectively. A proposed mechanism for the reaction is discussed.

A novel synthesis of β,β-dibromostyrenes

A new simple and efficient transformation of aromatic aldehydes to β,β-dibromostyrenes and arylbromoacetylenes is described. The olefination procedure was conducted under mild conditions and in good yields.
