Stereoselectiveoxidativecoupling of 10-hydroxy-1,2,3,4-tetrahydrophenanthrene derived from methyl 3-methoxy-2-naphthoate gave (−)-(S)-10,10′-dihydroxy-1,1′,2,2′,3,3′,4,4′-octahydro-9,9′-biphenanthryl which was converted into (+)-(S)-10,10′-dimethoxy-9,9′-biphenanthryl assigning the S configuration to (−)-10,10′-dihydroxy-9,9′-biphenanthryl.
衍生自 3-甲氧基-2-萘甲酸甲酯的 10-羟基-1,2,3,4-四氢菲的立体选择性氧化偶联得到 (-)-(S)-10,10'-二羟基-1,1',2, 2',3,3',4,4'-octahydro-9,9'-biphenanthyl 被转化为 (+)-(S)-10,10'-dimethoxy-9,9'-biphenanthyl 指定 S 构型(-)-10,10'-二羟基-9,9'-联菲基。
