Synthesis and Structure of Optically Active 1,12-Diethyl- and 1,12-Diisopropylbenzo[c]phenanthrenes: An Isopropyl Group Can Be Smaller than a Methyl Group
Synthesis and Structure of Optically Active 1,12-Diethyl- and 1,12-Diisopropylbenzo[c]phenanthrenes: An Isopropyl Group Can Be Smaller than a Methyl Group
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.
