N-tert-Butyl-N-2-pyridylhydroxylamines were synthesized from 2-halopyridines and 2-methyl-2-nitrosopropane using magnesium-halogen exchange. The use of Turbo Grignard generated the metallo-2-pyridyl intermediate more reliably than alkyllithium reagents. The hydroxylamines were characterized using NMR, electrochemistry, and density functional theory. Substitution of the pyridyl ring in the 3-, 4-, and 5-positions was used to vary the potential of the nitroxyl/oxoammonium redox couple by 0.95 V. DFT computations of the electrochemical properties agree with experiment and provide a toolset for the predictive design of pyridyl nitroxides.

The present invention is directed to substituted 3-aryl-5-aryl-[1,2,4]-oxadiazoles and analogs thereof, represented by the Formula I: wherein Ar1, Ar3, A, B and D are defined herein. The present invention also relates to the discovery that compounds having Formula I are activators of caspases and inducers of apoptosis. Therefore, the activators of caspases and inducers of apoptosis of this invention may be used to induce cell death in a variety of clinical conditions in which uncontrolled growth and spread of abnormal cells occurs.
Synthesis of thieno[2,3-b]quinoxalines from 2-haloquinoxalines

Thieno[2,3-b]quinoxalines were synthesized from 2-haloquinoxalines using palladium catalyst. The coupling of latter with alkynes and addition of one mol equivalent of bromine to the 2-alkynylquinoxalines thus produced was described. The resulting dibromid
