Starting from (+)-camphor-10-sulfonic acid (1) the chiral crystalline alcohols 3 and 11 were prepared in two steps. Lewis-acid-mediated [4+2]-additions of their acrylates to 1,3-dienes were studied. Notably, the crystalline acrylate 4 underwent TiCl2 (OiPr)2-promoted Diels-Alder addition to cyclopentadiene giving after recrystallization efficiently the pure (2R)-adduct 5.
