Reaction of tetracyanoethylene with α,β-unsaturated ketones was investigated. 3-R1-4-R2-6-R3-5-oxo-1,1,2,2-cyclohexanetetracarbonitriles, unsaturated tetracyanoalkanones, 3-R-5,5-dihydroxy-1,1,2,2-cyclohexanetetracarbonitriles, 1,2,2-tricyano-3-R-5-oxo-1-cyclohexanecarboxamides, 3-R1-4-R2-8-R3-5-hydroxy-7-oxo-6-azabicyclo[3.2.1]octane-1,2,2-tricarbonitriles were synthesized.
Abstract A stereospecific synthesis of enones 3 by coupling reaction of α-acetoxy alkyl methylvinylketones 2 and Gilman or Grignard reagents in the presence of a catalytic amount of copper (I) salt at low temperature, is described.
