Radical Cyclization of Polyenes Initiated by Attack of Trialkyltin or

Germanium Radical on an Ynone.

-The polyenes (I) successfully undergo radical multicyclization forming the tricyclic compounds (II), however, in low yields. In contrast, the substituted derivative (III) does not undergo multicyclization but gives the monocyclization product (VI). -(SPINO,
