Organic Syntheses

A solvent-free approach for organic synthesis is described which involves microwave (MW) exposure of neat reactants (undiluted) either in the presence of a catalyst or catalyzed by the surfaces of inexpensive and recyclable mineral supports such as alumina, silica, clay, or "doped" surfaces, namely, Fe(NO3)3-clay (clayfen), Cu(NO3)2-clay (claycop), NH2OH-clay, PhI(OAc)2-alumina, NaIO4-silica, MnO2-silica, and NaBH4-clay. A variety of deprotection, condensation, cyclization, oxidation, and reduction reactions are presented including the efficient one-pot assembly of heterocyclic molecules from in situ generated intermediates such as enamines and a-tosyloxyketones. The application of this solvent-free MW approach to multicomponent reactions is highlighted that can be adapted for high-speed parallel synthesis of the library of dihydropyrimidine-2(1H)-ones and imidazo [1,2-a]annulated pyridines, pyrazines, and pyrimidines.

Abstract:: In this review, we focused on the six- and pseudo six-component transformations in organic syntheses as a class of important and applicable MCRs. Although the MCRs usage in recent years is enhanced but the reports for more than five-component MCRs is still rare. In some cases this kinds of MCRs is the combination of some tandem named reactions which generated a union MCR. Preparation of multi-functionalized heterocycles, prevention of intermediate separation, reaction progressing in a one-pot continues manner, elevated total yield, high atom economy, and preparation of potent bioactive multi-cycles hetero-organics via construction of several new bonds are some highlighted features of MCRs. In this article we classified the mentioned six-component reactions based on reaction media. Another subdivision applied based on the thermal energy usage or ambient temperature. In fact two aspects of the green chemistry rules has been discussed.

The Impact

AbstractA large amount of CO has been detected above many SL9/Jupiter impacts. This gas was never detected before the collision. So, in our opinion, CO was released from a parent compound during the collision. We identify this compound as POM (polyoxymethylene), a formaldehyde (HCHO) polymer that, when suddenly heated, reformes monomeric HCHO. At temperatures higher than 1200°K HCHO cannot exist in molecular form and the most probable result of its decomposition is the formation of CO. At lower temperatures, HCHO can react with NH3 and/or HCN to form high UV-absorbing polymeric material. In our opinion, this kind of material has also to be taken in to account to explain the complex evolution of some SL9 impacts that we observed in CCD images taken with a blue filter.
