The chemical structures of the majority of FMs that have been studied in wastewater treatment are given in Figs. 1-3. Figure 1 shows a variety of FM structures that include alcohols, aldehydes, and ketones, including benzyl acetate (phenylmethyl ester acetic acid), methyl salicylate (2-hydroxy-methyl ester benzoic acid), methyl dihydrojasmonate (3-oxo-2-pentyl-methyl ester cyclopentaneacetic acid), terpineol (4-trimethyl-3-cyclohexene-1-methanol), benzyl salicylate (2-hydroxy-phenylmethyl ester benzoic acid), isobornyl acetate... 

In a recent modification of the second synthesis (50S) effected for fluvibactin (45) an o-xylene protection group was proposed (reaction of 2,3-dihydroxy-benzoic acid methyl ester with 1,2-di(bromomethyl)benzene) which could be removed later by hydrogenolysis. The formation of the oxazoline ring from protected DHB-L-threonine methyl ester was achieved with Mo(VI) catalysts (e.g. (NH4)2Mo04) without affecting the chiral centers. Derivatization of the primary amino groups of norspermidine with the protected DHB methyl ester was catalyzed by Sb(OC2115)3.

The opposite can be observed with acidic analytes as shown in Figure 2.18. Here, with classical RP and methanol at pH 3 the best selectivity and peak shapes were observed. On the other hand, with the shielded phases, acetonitrile gives the best separation. As already discussed, with shield phases the retention of nonpolar components (here peak 6 dimethyl phthalate) is reduced, whereas that of phenolic components (e.g., peak 5 p-hydroxy benzoic acid methyl ester) is increased.

A mixture of 5-chloromethyl salicylate, 3-chloro-2-methylpropene, potassium carbonate, and acetone was heated at reflux overnight. After cooling, the mixture was extracted with diethyl ether and ethyl acetate. The organic extracts were combined, washed twice with a 10% sodium chloride solution and water, dried over sodium sulfate, and concentrated in vacuum. The resulting liquid was vacuumed distilled. The fraction collected and the desired 5-chloro-2-(2-methyl-2-propenyloxy)benzoic acid, methyl ester was obtained. 

A mixture of the 2-hydroxy-5-chloro-3-(2-methyl-2-propenyl)benzoic acid, methyl ester and 1 L of methanol was saturated with 90% formic acid and then refluxed overnight. The solution was concentrated in vacuum, added to water, and extracted with ethyl acetate. The organic layer was washed with water, dried over sodium sulfate, and concentrated in vacuum, providing the desired 2,2-dimethyl-5-chloro-2,3-dihydrobenzofuran-7-carboxylic acid, methyl ester as an oil. 

The o-substituted benzoic acid methyl ester of formula (CH3)2NC6H4C02CH3 has been found to lose both the ester methyl and the amine methyl in metastable ion decompositions. It has been proposed that the bond cleavage to eliminate the ester methyl is accompanied by a hydrogen transfer from one of the other methyl groups to the carbonyl oxygen in a 7-membered cyclic transition state [83]. The mechanistic proposal rests upon isotope effects observed on substituting deuterium in methyl groups.
