Abstract: The conformationally rigid chiral ligand, trans-12-(pyridin-2-yl)-9,10-dihydro-9,10-ethanoanthracene-11-carboxylic acid ethyl ester, 1, was designed and synthesized in racemic form. Both isomers were successfully obtained in enantiomerically pure form through classical resolution using l-(+)-tartaric acid in acetonitrile. The nature of the diastereomeric complex formed in this resolution was elucidated using single crystal X-ray crystallographic studies. The absolute configuration of (+)-1 was unambiguously assigned as (11S,12S) by single crystal structural analysis of salt 5 formed from (+)-1 and l-(+)-tartaric acid. © 2009 Elsevier Ltd.
