Asymmetric Reduction of 3,5-Dinitroacetophenone Using CT Complexation with Optically Active 1,12-Dialkylbenzo[c]phenanthrenes

摘要

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.
