A modular route to nonracemic cyclo-NOBINs. Preparation of the parent ligand for homo- and heterogeneous catalysis

A sequence which combines a nonracemic tether, a naphthyl diol, and an aminonaphthol has been developed leading to the new ligand cyclo-NOBIN, which can easily be mounted onto polystyrene. Opportunities for extending the route to substituted cyclo-NOBINs are also discussed.
