Development of a C2-Symmetric Chiral aza Spirocyclic Diol

Abstract
A C-2-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 desymmet-rization of bisallylic amide were reported.
