γ-Alumina nano particle catalyzed multi component reaction of benzil, arylaldehyde and aryl amines afforded the highly substituted 1,2,4,5-tetraaryl imidazoles with good to excellent yield in less reaction time under the sonication as well as the conventional methods. Convenient operational simplicity, mild conditions and the reusability of catalyst were the other advantages of this developed p...

Carboxylesterases are ubiquitous proteins responsible for the detoxification of xenobiotics. However, these enzymes also activate prodrugs, such as the anticancer agents capecitabine and CPT-11. As a consequence, overexpression of carboxylesterases within tumor cells sensitizes these cells to CPT-11. We have recently identified two classes of carboxylesterase inhibitors based on either a benzil...

A novel synthesis of Iimidazo[1,2-c]quinazoline-5(6H)-thione framework was developed through a three-step reaction starting from benzil. The resulting (2-nitrophenyl)-4,5-diphenyl-1H-imidazole  from the reaction of benzil and different 2-nitrobenzaldehyde, reduction of nitro group and then cyclization reaction with carbon disulfide (CS2). All steps were carried out under easy and user-friendly ...

3,4-Di-O-benzil-1-O-metil-L-galactitol (3) foi sintetizado em 7 etapas a partir de 1,2:3,4-diO-isopropilideno-D-galactopiranose (4). A síntese envolve a metilação do HO-6 de 4, seguida de metanólise para a mistura do 6-O-metil-D-galactopiranosídeo de metila (6, produto principal) e do análogo -furanosídico 8. O composto 6 foi convertido no derivado 3,4-O-isopropilidênico 9 e o grupo OH livre fo...

The germene Mes(2)Ge=CR(2) (Mes = 2,4,6-trimethylphenyl, CR(2) = fluorenylidene) reacts with various benzil derivatives to lead to germanium-containing bicyclic epoxides by an unexpected new type of epoxidation reaction.
