With oxygen-substituted ring systems

Retinoids with Oxygen-Substituted Ring Systems... [Pg.72]

Furthermore, one might expect that electron-withdrawing substituents on aromatic systems (e.g., positive a values) make the -electrons of the ring system less nucleophilic and thus the rate of attack of the electrophilic oxygen on that ring slower. This is consistent with observations on a series of substituted benzoates where steric factors do not dominate (Knackmuss, 1981) ... [Pg.716]
