The side-chain and substituent control of stereoselectivity, periselectivity and regioselectivity in the intramolecular [8 + 6] and [4 + 2] cycloadditions of electron-deficient 8-cyanoheptafulvenes connected at C-8 by trimethylene or tetramethylene chains to C-6 of electron-rich 6-methyl- or 6-phenylfulvenes are discussed.
