Résumé

Chemistry Chemistry, Multidisciplinary Physical Sciences Science & Technology
Allyltitanocene complexes can be generated by reacting pentafulvenes with DIBAL-H and Cp2TiCl2. Their coupling with aldehydes affords homoallylic alcohols in a highly regio- and stereoselective manner. The potential of this method for the stereoselective synthesis of cyclopentane derivatives is illustrated.
