The sequential reactions of tetrazoles with bromoalkynes for the synthesis of (Z)-N-(2-bromo-1-vinyl)-N-arylcyanamides and 2-arylindoles

2-Arylindoles were prepared by a sequential reaction of Ag-catalyzed alpha-addition-Pd-catalyzed C-H bond functionalization of tetrazoles with bromoalkynes. A stereocontrolled Ag-catalyzed alpha-addition reaction of tetrazoles with bromoalkynes underwent smoothly to generate (Z)-N-(2-bromo-1- vinyl)-N-arylcyanamides, which were subsequently converted into 2-arylindoles through an intramolecular cyclization by Pd-catalyzed direct C-H bond functionalizations.

Esters of quinoxaline 1?4-Di-N-oxide with cytotoxic activity on tumor cell lines based on NCI-60 panel

Quinoxalines display diverse and interesting pharmacological activities as antibacterial, antiviral, antiparasitic and anticancer agents. Particularly, their 1?4-di-N-oxide derivatives have proved to be cytotoxic agents that are active under hypoxic conditions as that of solid tumours. A new series of quinoxaline 1?4-di-N-oxide substitutes at 7-position with esters group were synthetized and characterized by infrared (IR), proton nuclear magnetic resonance (1H-NMR), spectroscopy, and elemental analysis. Seventeen derivatives (M1-M3, E1-E8, P1-P3 and DR1-DR3) were selected and evaluated for antitumor activities using the NCI-60 human tumor cell lines screen. Results showed that E7, P3 and E6 were the most active compounds against the cell lines tested. Substitutions at 7-position with esters group not necessarily affect the biological activity, but the nature of the esters group could exert an influence on the selectivity. Additionally, substitutions at 2-position influenced the cytotoxic activity of the compounds.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 23088-23-5 is helpful to your research. Synthetic Route of 23088-23-5
