Synthesis of enantiomerically pure helicene like bis-oxazines from atropisomeric 7,7’-dihydroxy BINOL: Preliminary measurements of the circularly polarized luminescence
[Image: see text] Racemic sample of 2,2’,7,7’-tetrahydroxy-1,1’-binaphthyl was resolved with (S)-proline and the separated enantiomers were independently converted to atropisomeric bis-oxazines by aromatic Mannich reaction. These chirally pure oxazines were then converted to the helicene like cyclic...
