Diastereoselective Addition of Allyltitanocenes to Cyclic Enones

Diastereoselective Addition of Allyltitanocenes to Cyclic Enones

The reaction of allyltitanocenes with five- to seven-membered cyclic enones proceeded with good to high diastereoselectivity depending on the ring size of enones. The stereochemistry of the major isomers produced by the reaction of cinnamyltitanocene was opposite to that of crotyltitanocene.
