Asymmetric reduction of 3,5-dinitroacetophenone using CT complexation with optically active 1,12-dialkylbenzo[c]phenanthrenes
Optically active 1,12-dialkylbenzo[c]phenanthrene-5,8-dimethanols and its derivatives formed charge-transfer (CT) complexes with 3,5-dinitroacetophenone in solution, and the treatment of the complexes with borohydrides provided the optically active alcohol up to 13% ee.
