Free carboxylic acids such as benzoic acid, phenylacetic acid, or 4-hydroxyben-zoic acid 297 are converted on heating with HMDS 2 or OMCTS 52, via their N,0-bis(silylated) amides such as 22a, into nitriles such as 298 [99, 100] (Scheme 4.38). [Pg.66]

The hydroxybenzoic acid derivatives (HBAs) are phenolic compounds with a general structure C6-C1. The related C6-Ci acids (phenylacetic acids) occur occasionally as minor components of foods. [Pg.258]

Taurine conjugation with bile acids, phenylacetic acid, and indolylacetic acid seems to be a minor process in most species, but in the pigeon and ferret, it occurs extensively. Other infrequently reported conjugations include serine conjugation of xanthurenic acid in rats excretion of quinaldic acid as quinaldylglycyltaurine and quinaldylglycylglycine in the urine of the cat, but not of the rat or rabbit and conversion of furfural to furylacrylie acid in the dog and rabbit, but not in the rat, hen, or human.

Model Parent Compound Series. Experimental partition coefficient data for a variety of substituted benzenes and seven other related parent compound series (phenoxyacetic acid, phenylacetic acid, benzoic acid, benzyl alcohol, phenol, aniline, nitrobenzene) were reported in 1964 by Fujita et al. (II). The ir values (see Equation 3) derived for individual substituents in each of the above-mentioned parent compound series have since been frequently used (with varying degrees of success) by many investigators to approximate tt values for the corresponding substituents in other related parent compounds for which no experimental partitioning data are available. For example, Hansch and Deutsch (26), in a correlation study of structure—activity relationships in cholinesterase inhibitors, used tr values derived for aromatic ring substituents (X) in the phenoxyacetic acid series...

Although the pKa s of phenoxyacetic acid, phenylacetic acid, TFMS, and aniline are all quite similar, differing by less than 1.5 pK units for the most extreme comparison (phenoxyacetic acid vs. aniline), this similarity ends when the partitioning behavior of these same parent compounds is compared. Whereas the logarithm of the octanol/water partition coefficient (F) varies only from log F = 0.90 for aniline to log F = 1.41 for phenylacetic acid, TFMS (log F = 3.05) is 1.6 orders of magnitude more lipophilic than phenylacetic acid, the most hydrophobic of the other parent compounds exhibiting a similar pKa. If the w values for the side chains of the parent compounds listed in Table III are calculated using Equation 5 as shown on p. 196 ... [Pg.200]

Ketorolac tromethamine is contraindicated in patients while wearing soft contact lenses. Caution should be used with patients who have previously exhibited sensitivity to acetylsalicylic acid,phenylacetic acid derivatives, and other NSAIDs because a potential exists for cross-sensitivity. [Pg.259]

In 1926 Frits Went, a student in the Netherlands, detected that the tips of wheat seedlings contained a substance that caused the seedlings to bend toward the light. The identity of the substance, which was given the name auxin from the Greek auxein (meaning "to increase"), was unknown. A few years later it was shown that auxin was indole-3-acetic acid (I A A). Today, four natural auxins are known. Besides IAA there are indole-3-butyric acid, phenylacetic acid, and 4-chloroindole-3-acetic acid. (It is quite interesting to find a chlorinated aromatic substance as a natural substance. It is synthesized... [Pg.155]

Photochemical decomposition of pyrethrins and synthetic analogues can be slowed down by the simultaneous use of antioxidants and photoscreens. In the course of decomposition, chrysanthemic acid, phenylacetic acid, benzyl alcohol, benzaldehyde and benzoic acid are formed from resmethrin (32) as decomposition products and, at the same time, the furan ring undergoes an oxidative transformation (Ueda et al., 1974) ...
