Highly efficient and practical resolution of 2,3:6,7- dibenzobicyclo[3.3.1]nona-2,6-diene-4,8-dione and stereoselective synthesis of its chiral diamine derivatives

摘要

Highly efficient and practical resolution of 2,3:6,7-dibenzobicyclo[3.3.1]nona-2,6-diene-4,8-dione by inclusion complexation with commercially available enantiopure 1,1’-bi-2-naphthol is reported. The structure of the 1 : 1 inclusion complex of the diketone and BINOL was confirmed by single crystal X-ray crystallography.
