induction in the iodocarbocyclizationreaction of 4-pentenylmalonate derivatives having a stereogenic center at an allylic or a homoallylic position has been investigated. The iodocarbocyclizationreactions of 3-oxy-4-pentenylmalonate derivatives proceeded with high cis-selectivity through stereoelectronic control of the oxygenated substituent at an allylic position. In the reaction of (S)-2-siloxy-4-pentenylmalonate

The iodocarbocyclization of 4-pentenylmalonate I having a substituent at the 2 or 3 position effectively proceeded by treating I with I-2 and Ti(OtBu)(4) in the presence of CuO. Stereoelectronic effect of the subtituent at allylic position on diastereoselectivity was notable. As an application of the present reaction, the efficient synthesis of cyclosarkomycin 7 was achieved.
