Calculate Digit Verification of CAS Registry Number 97478-07:
(7*9)+(6*7)+(5*4)+(4*7)+(3*8)+(2*0)+(1*7)=184
184 % 10 = 4

ENANTIOMERS OF STERICALLY HINDERED N-ARYL-4-PYRIDONES. CHROMATOGRAPHIC ENRICHMENT AND THERMAL INTERCONVERSION

Mintas, M.,Orhanovic, Z.,Jakopcic, K.,Koller, H.,Stuehler, G.,Mannschreck, A.

, p. 229 - 236 (2007/10/02)

N-aryl-4-pyridones 1-6 were synthesized by condensation of the corresponding 4-pyrone with anilines.The enrichment of the enantiomers was achieved by liquid chromatography on triacetylcellulose, enantiomeric purities of (+)-1 and (+)-2 being measured by 1H NMR in the presence of an optically active auxiliary.Barriers to partial rotation about the C-N bond in 1-4 were determined and compared with corresponding biphenyls.
