Cahn-Ingold-Prelog notation (Section 7.6) System for specifying absolute configuration as / or S on the basis of the order in which atoms or groups are attached to a chirality center. Groups are ranked in order of precedence according to rules based on atomic number. [Pg.1278]

Applying the Cahn-Ingold-Prelog notational system described in Section 7.6 to the product, the order of decreasing precedence is... [Pg.356]

In its original form, the Cahn-Ingold-Prelog notation for stereoisomers is excessively cumbersome for cyclitols, but it might possibly serve to classify the lowest numbered asymmetric center in each optically active cyclitol molecule. ... [Pg.15]

Upon application of the Cahn-Ingold-Prelog notation (36) the carbonyl group of the acyl side chain at C-4 in the isohumulones has priority over the carbonyl group at C-3, because this carbonyl occurs almost exclusively in the enol form. This feature has been proved by study of the CD spectra. To evaluate the enolization pattern, the CD behaviour of compounds with fixed enolization has to be investigated first. The methyl enol ethers of the dihydrodeoxohumulinic acids (74-77) are suitable for this purpose. [Pg.98]
