Trans -6-bromo-5-hydroxy-5,6,7,8-tetrahydroquinoline enantiomers have been resolved via their dibenzoyltartrate salt diastereoisomers. X-ray crystallographic analysis of the (+)-dibenzoyltartrate salt obtained from reaction of (+)-dibenzoyltartaric acid and (−)-trans-6-bromo-5-hydroxy-5,6,7,8-tetrahydro-quinoline, when allied to a stereochemical correlation sequence linking the arene oxide, trans -dihydrodiol and cis -dihydrodiol enantiomers, provides an unequivocal assignment of absolute configuration for these quinoline metabolites. |
