Background: Molecular organic photochemistry is concerned with the description of physical and chemical processes generated upon the absorption of photons by organic molecules. Recently, it has become an important part of many areas of science: chemistry, biology, biochemistry, medicine, biophysics, material science, analytical chemistry, among others. Many synthetic chemists are using photochemical reactions Read More

The first attempts at microwave-assisted (MW) syntheses of bile acid derivatives were performed in domestic MW appliances. However, the reproducibility of these syntheses, which were performed in uncontrolled conditions, was very low. In the first part of this overview, compounds synthesized under such conditions are presented. Consequently, with the development of MW technology, MW-assisted reactions in MW Read More

Diactivated cyclopropanes containing two geminal electron withdrawing groups, commonly called as ‘Doubly Activated Cyclopropanes’ are useful synthons for the synthesis of many interesting natural products and functionalized molecules. These geminal electron withdrawing groups (EWG’s) facilitate the regioselective ring opening of cyclopropanes by polarizing the C-C bond adjacent to it. This polarization also allows them to Read More

Magnetically separable Brønsted acidic catalysts combine the advantages of high efficiency of homogeneous Brønsted acidic catalyst with the ease of magnetic separation from the reaction medium. In addition to their ease of separation, the magnetically separable Brønsted acidic catalysts also possess high stability towards air and moisture, facile functionalization and tunable hydrophobic properties. This review portrays the app Read More

Neurodegenerative diseases (NDDs) are characterized by a progressive deterioration of the motor and/or cognitive function, that are often accompanied by psychiatric disorders, caused by a selective loss of neurons in the central nervous system. Among the NDDs we can mention Alzheimer’s disease (AD), Parkinson’s disease (PD), Huntington’s disease (HD), amyotrophic lateral sclerosis (ALS), spinocerebellar ataxia Read More
