Electrochemical conversions of alkyl alkylidenecyanoacetates into 3-substituted dialkyl 1,2-dicyanocyclopropane-1,2-dicarboxylates
摘要:
Electrolysis of alkyl alkylidenecyanoacetates in an undivided cell in the presence of alkali metal halides as mediators afforded 3-substituted dialkyl 1,2-dicyanocyclopropane-1,2-dicarboxylates in 50-85% yields.

Compound that is an inhibitor of at least one of the A2A and A2B adenosine receptors, and compositions containing the compound and methods for synthesizing the compound, are described herein. The use of such compound and compositions for the treatment of a diverse array of diseases, disorders, and conditions, including cancer- and immune-related disorders that are mediated, at least in part, by the adenosine A2A receptor and/or the adenosine A2B receptor.

The kinetics of the reaction of ( + )-3-methyl cyclohexanone with malononitrile were studied in benzene at 25°, in the presence of hexylamine-acetic acid mixtures. Hexylamine gives an imine with cyclohexanone in an acid-catalysed step. This imine then reacts quickly with malononitrile. A rate law of zero order in malononitrile is observed. Separate kinetic results obtained for the formation of the
