The Ullmann Coupling Reaction of Axially Chiral (S)-2,2'-Bis(1-iodo-2-naphtyloxycarbonyl)-1.1'-binaphthyl

Article abstract of DOI:10.1246/bcsj.58.1345

The intramolecular Ullmann coupling of the title diester proceeded in low yield but with virtually complete asymmetric induction in joining the two naphthyl units leading to the 12-membered cyclic diester of (S,S)-configuration, which is the same diastereoisomer obtained from the reaction of (S)-2,2'-bis(1-bromo-2-naphthoyloxy)-1,1'-binaphthyl.
