The titanium-mediated intramolecular cyclopropanation of ω-allylic succinates leads only to cyclopropanol, arising from exclusive reactivity of one ester function. As an extension of this methodology, the diastereoselectivesynthesis of highly functionalized pyrrolidinone has been realized from cheap commercially available L-aspartic acid.
