Carménère is the emblematic grape of Chile. Recent studies indicate that it has a different polyphenolic profile than other commercial varieties of grape among other factors, due to its long maturation period. The grape and wine of Carménère stand out for having high concentrations of anthocyanins (malvidin), flavonols (quercetin and myricetin) and flavanols (catechin, epicatechin and epigallocatechin). These compoun Read More

Quinolines and their derivatives are an important class of heterocyclic compounds that occur widely in natural products, drugs and biologically active compounds. A large variety of quinolines have displayed interesting physiological activities and found attractive applications as pharmaceuticals and agrochemicals. In accordance with these useful properties and related applications as above-mentioned, a numbe Read More

Epoxides and aziridines are very useful small heterocycles. The synthesis of these threemembered heterocycles including those derived from α,β-unsaturated aldehydes is a dynamic area of research. Among numerous approaches to construction of three-membered cycles with O- or Nheteroatoms are metallo- and organocatalysis. This review summarizes and highlights the methods for the synthesis of epoxides and a Read More

This review surveys carbon-carbon bond forming reactions of acetylene radical-cations, generated under the one-electron oxidation of alkynes in the systems lead dioxide (PbO2) – strong acid (CF3CO2H, FSO3H, HF). The oxidative dimerization proceeds very regioselectively at acetylene carbons. This approach is a powerful synthetic tool, leading to complex and polyfunctional organic molecules, such as, dicarbonyl- and t Read More

Taxus is a genus of 12 species mainly distributed in the Northern Hemisphere, with four species in North America, one in Europe, and the remaining native to Southeast Asia. Taxus contains numerous compounds of taxane derivatives, polysaccharides, and flavanoids. The compound with the greatest significance for humans is an oxygen-rich diterpene called taxol, which can be used as an inhibitor of cancer cell growth. Many Read More

Due to the widespread application of nanoparticles they can be utilized as a catalyst in various organic reactions today. Recent research has been directed towards the utilization of TiO2 nanoparticles which have emerged as an attractive multi-functional material. This paper aims to present a short review on the catalytic potential of TiO2 nanoparticles in a wide range of reactions and syntheses of bioactive heterocycles.

Electrochemical reactions, with clean power, can prepare valuable chemicals directly and improve yield efficiency and reduce the three wastes, which have become one of the green methodologies. Ionic liquids have attracted increasing attention in the area of electrochemistry due to their significant properties including good chemical and thermal stability, wide liquid temperature range, considerable ionic conductivity, nonfl Read More
