Synthesis of planar-chiral paracyclophanes via samarium(II)-catalyzed intramolecular pinacol coupling

(Chemical Equation Presented) A series of [n]jparacyclophanediols (n = 8-12) was synthesized by samarium-catalyzed pinacol coupling for their ansa-bridge formation. Enantiomerically pure [n]jparacyclophane esters were derived from the diols in a several steps via chiral resolution (for n = 10) or via crystallization-induced asymmetric transformation (for n = 11) by using amino alcohol auxiliaries and their selective cleavages.
