title: Fumarate of (S,S)-alpha,alpha'-bis(trifluoromethyl)-1,8-anthracenedimethanol. A chiral macrocycle for the Diels-Alder reaction with cyclopentadiene.
abstract: The synthesis and structural study of the fumarate of (S,S)-alpha,alpha'-bis(trifluoromethyl)-1,8-anthracenedimethanol by NMR spectroscopy are reported. The conformational study of the 13-membered macrocycle is presented. The cited alcohol is assayed as a chiral auxiliary in a Diels-Alder reaction with cyclopentadiene, and after methanolysis, provides the norbornene derivative with high enantioselectivity.
