We truly appreciate your continued support for TCI.

Sincerely yours,

New 2014-2015 Fine Chemicals Catalog will be available in April

The new catalog includes over 23,000 research chemicals, with 1,500 new products for synthetic organic chemistry, materials chemistry, bioscience and analytical science.  Also the catalog contains chemical structure formulas, extensive physical and chemical data, and hazard information, etc.

TCIMAIL No.160 - Paper Magazine

In the TCIMAIL, we mainly introduce our new reagents in the fields of Synthetic Organic Chemistry, Materials Chemistry, Bioscience and Analytical Science.  Examples of application and use are explained in an easy to understand way, using various schemes and charts.  The TCIMAIL also contains technical papers contributed by leading professors and scientists.

Flow Generation and Reaction of Diazomethane Using a Gas-Permeable Teflon Tube-in-Tube Reactor

Kappe et al. have reported a continuous generation, separation, and reactions of anhydrous diazomethane in a tube-in-tube continuous flow reactor.  Diazomethane is formed in the inner tube by the treatment of N-methyl-N-nitroso-p-toluenesulfonamide with KOH, and then diffuses through the gas-permeable inner tube into the outer chamber and subsequently reacts with reactants dissolved in the solution carried within.  This synthetic device is applied to methyl esterifications, cyclopropanations, [2+3] cycloadditions and Arndt-Eistert reactions. The tube-in-tube, made of gas-permeable Teflon AF-2400 (inner) and impermeable PTFE (outer), is commercially available.

Product Highlight

An Efficient N-Heterocyclic Carbene Precursor for the Asymmetric Intramolecular Stetter Reaction

T. Rovis et al. has developed a chiral bicyclic triazolium salt (1) and has used it as a N-heterocyclic carbene precursor. 1 affords the related N-heterocyclic carbene 2 by a deprotonation under basic conditions.  The chemical property of 2 is in showing a lower basicity effected by the electron-deficient 4-(trifluoromethyl)phenyl group of 2. Therefore, in an intramolecular Stetter reaction using 2 as an organocatalyst, the reactions proceed with high enantio- and diastereoselectivities even when substances easy to epimerize are employed.  In addition, in a case using substances which easily proceed to intramolecular aldol condensations, the intramolecular Stetter reactions preferentially proceed. Furthermore, aliphatic aldehydes can be used and afford the desired 1,4-dicarbonyl compounds with high stereoselectivities.  Thus, 1 is an efficient asymmetric organocatalyst because of its availability for various substances.
