Abstract

We report the enantioselective synthesis of azaborole helicenes from enantioenriched axially chiral precursors. The borylation/metal-exchange reaction sequence affords the target compounds with full transfer of chirality from the corresponding biaryls. Experimental studies provided insights into the configurational stability of the heterobiaryls and their (chir)optical properties. The structure of the -phenyl-substituted helicene was unambiguously confirmed by single-crystal X-ray analysis. [ABSTRACT FROM AUTHOR]
