Summary

  1. 1.

    A study was made of structural orientation in the diene condensation of trans-piperylene with the nitro dienophiles RCH=CHNO2, in which R=H, CH3, C6H5, CCl3, COOCH3.

     
  2. 2.

    In the condensation of trans-piperylene with nitroethylene(R=H)the only reaction product is the ortho isomer.

     
  3. 3.

    In the condensation of trans-piperylene with 1,2-disubstituted nitro dienophiles (R=CH3, C6H5, CCl3, COOCH3) in all cases two structurally isomeric adducts are formed with a great predominance of the ortho isomer.
