OPTICALLY-ACTIVE AROMATICS POSSESSING HELICAL CHIRALITY - ONE-POT SYNTHESIS, OPTICAL RESOLUTION AND CRYSTAL-STRUCTURE OF 13,14-DIMETHYLDIBENZO[B,J][4,7]PHENANTHROLINE AND ITS DIHYDRO FORM AS A NOVEL CHIRAL BUILDING-BLOCK
Y. Tanaka et al., OPTICALLY-ACTIVE AROMATICS POSSESSING HELICAL CHIRALITY - ONE-POT SYNTHESIS, OPTICAL RESOLUTION AND CRYSTAL-STRUCTURE OF 13,14-DIMETHYLDIBENZO[B,J][4,7]PHENANTHROLINE AND ITS DIHYDRO FORM AS A NOVEL CHIRAL BUILDING-BLOCK, Journal of the Chemical Society. Perkin transactions. I (Print), (16), 1998, pp. 2471-2472
Helical aromatics, 13,14-dimethyldibenzo[b,j][4,7]phenanthroline 1 and
its dihydro form 2 were synthesized via a one-step reaction, resolved
into each of the enantiomers by HPLC and their single crystal structu
res were determined.
