Catalytic C(sp(2))-C(sp(3)) Bond Formation of Methoxyarenes by the Organic Superbase t-Bu-P4

The organic superbase catalyst t-Bu-P4 achieves nucleophilic aromatic substitution of methoxyarenes with alkanenitrile pronucleophiles. A variety of functional groups [cyano, nitro, (non)enolizable ketone, chloride, and amide moieties] are allowed on methoxyarenes. Moreover, an array of alkanenitriles with/without an aryl moiety at the nitrile alpha-position can be employed. The system also features no requirement of a stoichiometric base, MeOH (not salt waste) formation as a byproduct, and the production of congested quaternary carbon centers.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 1953-02-2 help many people in the next few years. Product Details of 1953-02-2.

Dicumyl Peroxide used as curing Agent for different Types of Rubber Matrices Part I: Effect of Temperature

Several elastomers were cured with dicumyl peroxide at different vulcanization temperatures. The focus of the work was the investigation of the influence of curing temperature on curing characteristics of rubber compounds. Subsequently, crosslink density and physical mechanical properties of vulcanizates were evaluated. The results demonstrated that higher curing temperatures lead to a total acceleration of cross-linking process. The effect of temperature on the crosslink density was low and was dependent on the structure of tested rubbers. Physicalmechanical properties of vulcanizates were almost not influenced by curing temperature.

Short synthesis of 4-aryl-3-pyrrolin-2-ones

A three step, convergent synthesis of 4-aryl-3-pyrrolin-2-ones from a tetramic acid has been developed. The key transformation utilized a Suzuki-Miyaura cross-coupling reaction between a 4-tosyloxy-3-pyrrolin-2-one and an arylboronic acid. This work also provides access to 4-arylpyrrolidin-2-ones, cyclic analogs of gamma-aminobutyric acid (GABA). Hydrogenation of 4-(4′-chloro-phenyl)-3-pyrrolin-2-one proceeded smoothly to give baclofen lactam. (c) 2006 Elsevier Ltd. All rights reserved.

Visible-Light-Promoted Metal-Free Synthesis of (Hetero)Aromatic Nitriles from C(sp(3))-H Bonds**

The metal-free activation of C(sp(3))-H bonds to value-added products is of paramount importance in organic synthesis. We report the use of the commercially available organic dye 2,4,6-triphenylpyrylium tetrafluoroborate (TPP) for the conversion of methylarenes to the corresponding aryl nitriles via a photocatalytic process. Applying this methodology, a variety of cyanobenzenes have been synthesized in good to excellent yield under metal- and cyanide-free conditions. We demonstrate the scope of the method with over 50 examples including late-stage functionalization of drug molecules (celecoxib) and complex structures such as l-menthol, amino acids, and cholesterol derivatives. Furthermore, the presented synthetic protocol is applicable for gram-scale reactions. In addition to methylarenes, selected examples for the cyanation of aldehydes, alcohols and oximes are demonstrated as well. Detailed mechanistic investigations have been carried out using time-resolved luminescence quenching studies, control experiments, and NMR spectroscopy as well as kinetic studies, all supporting the proposed catalytic cycle.

An enantioselective formal synthesis of the proteasome inhibitor (+)-lactacystin

An enantioselective formal synthesis of the proteasome inhibitor (+)-lactacystim has been achieved using an alkylidene carbene 1,5-CH insertion reaction as a key step. The key cyclisation precursor was synthesised in high diastereomeric excess using a combination of known procedures, with the two key asymmetric centres being introduced via a Sharpless asymmetric epoxidation reaction. KHMDS induced 1,5-CH insertion produced a 3-pyrroline product, which was oxidised to the corresponding 3-pyrrolin-2-one using (1) TPAP/NMO; (2) NaCIO2; (3) NaBH4. The formal synthesis was then completed with a few standard functional group interconversions. (C) 2002 Published by Elsevier Science Ltd.

Intermolecularly hydrogen-bonded dimeric helices: tripyrrindiones

A rare and unusual class of tripyrrolic compounds, violet-colored tripyrrin-1,14-diones, can be prepared easily and in moderately high yields from base (piperidine)-catalyzed condensation of 3-pyrrolin-2-ones with 2,5-diformylpyrroles. Dipyrrinones adopt the all-syn-Z conformation leading to helical, lock-washer like structures, which form dimers that are held together by intermolecular hydrogen bonds in nonpolar solvents and in the crystal. Strong bathochromic spectral shifts of the tripyrrindione similar to 480 nm long wavelength UV-visible absorption band are seen with added base: DBU, 615 nm; TFA, 573 nm; and Zn(OAc)(2), 586 nm.
