The iodocarbocyclization reactions of 4-pentenylmalonate derivatives using 20 mol% of the chiral titanium complex in the presence of 12 end 2,6-dimethoxypyridine proceeded with high enantioselectivity to give good yields of cyclopentane derivatives. The origin of enantioselectivity in the present reaction is discussed on the basis of X-ray crystal structural data of the chiral titanium complex from acetylacetone, chiral dial and Ti(IV).
