Direct and facile bromination at the 5- and 5'-positions of (R)-6,6'-dialkyl- and (R)-6,6'-diaryl-2,2'-binaphthols.
[摘要]:(R)-6,6'-Dibutyl-, -bis(4-methylphenyl)-, -bis(3,5-dimethylphenyl)-, and -bis[4-(trifluoromethyl)phenyl]-5,5'-dibromo-2,2'-binaphthol were synthesized from (R)-1,1'-bi-2-naphthol by a 5-step reaction in excellent yields under mild conditions.
