Abstract

Abstract Versatility of titanium: Titanocene (III) complexes catalyze Barbier-type allylations, intramolecular crotylations (cyclizations), and prenylations of a wide range of aldehydes and ketones. These reactions take place at RT under mild conditions compatible with many functional groups; provide good yields of open-chain and cyclic homoallylic alcohols, including heterocyclic derivatives; and can be conducted enantioselectively by using ...
