Nitrogen-containing heterocycles (NCH), constitute an important group of molecules, which are widely extended in whole chemical space. These compounds are of great interest due to their diverse biological activities. Currently, many compounds derived from NCH are used as powerful drugs for the treatment of diseases ranging from bactericides to anticancer agents. During last decade, the enantioselective synthesis o Read More

This review article is focused on the synthesis of compounds with quinazolinones and benzo di/triazepine scaffolds. These invaluable derivatives are of great interest in medicinal and pharmaceutical studies because of their important biological properties. Quinazolinones have diverse applications due to their antibacterial, analgesic, antiinflammatory, antifungal, antimalarial, antihypertensive, CNS depressant, anticonvulsant, antihi Read More

Nitro hydrocarbons as inexpensive, easily available, and relatively stable organic intermediates have aroused great attention in various functional group transformations over the past several decades. The electron-withdrawing action of the nitro group can act as a transient leaving group to efficiently transform into the other important functionalities. Nitro compounds are easily prepared through simple synthetic reactions fro Read More

Bromopyridines, bromotiophenes and 3-bromofuran were reacted with diphenylphosphine oxide or diethyl phosphite under microwave irradiation using Pd(OAc)2 as the catalyst precursor together with some excess of the >P(O)H reagent. Hence, there was no need for the usual mono- and bidentate P-ligands. The >P(O)-functionalized heterocycles were obtained in variable (55-95%) yields. The results of our “green” protoco Read More

Triepoxides were synthesized for the first time in high yields (80-85%) by oxidation of substituted bicyclo[4.2.2]deca-2,4,7,9-tetraenes, bicyclo[4.2.2]deca-2,4,7-trienes, and tricyclo[9.4.2.02,10]heptadeca-2,12,14,16-tetraene with an excess of m-chloroperbenzoic acid. The structures of the epoxy derivatives were reliably proved using modern spectral methods and X-ray diffraction analysis. A high antitumor activity in Read More
