Starting from (R)-(+)- and from (S)-(−)-camphor the chiral alcohols 1, 2 and 3 have been prepared; their acrylates II underwent TiCl₂(OR)₂-promoted Diels-Alder additions to cyclopentadiene giving efficiently in a predictable manner either the (2R)- or the (2S)-adducts III with up to virtually quantitative asymmetric induction.
