Abstract
A C2-symmetric chiral spirocyclic diol aza-SPINOL containing a spirooxindole scaffold has been designed, synthesized, and optically resolved. The product could be synthesized on gram scale in an overall yield of 22%. Moreover, elaborations of aza-SPINOL to other chiral ligands as well as the preliminary investigation of the related bisphosphine ligand in the desymmetrization of bisallylic amide were reported.
