New Trifluoromethylated Pyridazines By Reductive Cyclization of Vinyldiazomethanes Bearing a Carbonyl Group

Primary tabs

Guillaume, M. Janousek, Z. Viehe, HG.

The synthesis of new vinyldiazomethanes from ethyl 2-diazo-4,4,4-trifluoroacetoacetate and Wittig or Horner-Emmons-Wadsworth (HEW) reagents is described. Vinyldiazomethanes which have a double bond bearing a carbonyl group undergo reductive cyclization in the presence of triphenylphosphine providing a new route to the pyridazine chemistry.
