The enzymatic process was carried out with a slurry of (E)-methyl 2-(3-(3-(2-(7-chloroquinolin-2-yl)vinyl)phaiyl)-3-oxopropyl)benzoate 79 (230kg) in a mixture of isopropyl alcohol (5 vol), toluene (1 vol), and triethanolamine buffer of pH 8.0 (3 vol). KRED CDX-026 (92kg) and the cofactor NADP-Na (023kg) were added to the reaction mixture, and the reaction was carried out at 40-45°C under stirring for 40-45h. From the reaction mixture, the crude (S)-2-[3-2[7-chloro-2-quinolinyl]ethenyl]phenyl-3-hydrox5q)ropyl] benzoic acid methyl ester 80 was obtained, which was purified by recrystallization to obtain pme product 80 as monohydrate 3 (233 kg, 97.2% yield, >99.9% ee) [109,110]. 

Fig. 5.1. A sample of floral scent compounds. (1) Substituted methyl esters of benzoic acid. The ester smells unpleasantly sweet when R = H (methyl benzoate), of wintergreen when R = OH (methyl salicylate), and of concord grape when R = NH2 (methyl anthranylate). Odorants with unusual origins and biological functions include the homoterpene 4,8-dimethyl-1,3,7-nonatriene (2) and the wet-earth compound geosmin (3). Some ubiquitous fragrance compounds are ben-zaldehyde (4), benzyl alcohol (5), indole (6), (S)-linalool (7), ( )-/ -ocimene (8), and of-farnesene (9).

Ethyl benzoate hydrogen chloride as a catalyst). Pass dry hydrogen chloride (Section 11,48,1) into a 600 ml. round-bottomed flask containing 116 g. (145 ml.) of absolute ethyl alcohol, cooled in an ice bath, until the increase in weight is 6 g. Add 30 g. of benzoic acid and reflux the mixture for 4 hours. Isolate the pure ester, b.p. 212-214°, as described for Methyl Benzoate. The yield is 32 g.

Ethyl Benzoate.—This ester has not been found, so far, to occur naturally in essential oils. It has, however, been prepared by synthetic processes, for example, by condensing ethyl alcohol with benzoic acid by means of dry hydrochloric acid gas. Its odour is very similar to that of methyl benzoate (q.v.), but not quite so strong. It is an oil of specific gravity I OfilO, refractive index 1 5055, and boiling-point 213° at 745 mm. It is soluble in two volumes of 70 per cent, alcohol.

Methyl salicylate 144 (Structure 4.44), the main constituent of wintergreen oil, is derived from benzoic acid. Other important esters are linalyl acetate 145, benzyl benzoate 146 and benzyl isobutyrate 147. 

An optimised enzymatic synthesis of methyl benzoate in an organic medium was reported by Leszczak and Tran-Minh [43]. Methyl benzoate is part of the aroma of some exotic fruits and berries. The ester has been produced by direct esterification of benzoic acid with methanol in hexane/toluene catalysed by lipase from Candida rugosa. 

Increases in substrate levels that were accidentally produced by metabolic engineering also resulted in an olfaction-detectable increase in the methyl benzoate emission in transgenic carnation [30]. The metabolic flux from the anthocy-anin pathway was redirected towards benzoic acid, the methyl ester precursor, by antisense suppression of the flavanone 3-hydroxylase. 

Methyl benzoate, [93-58-3], CTfCOOCI Ig, bp, 198—200°C at 101.3 kPa d [ , 1.094 n], 1.5205. Insoluble in water, this is a colorless, transparent liquid solidifying at about 15°C. Methyl benzoate is prepared by the direct esterification of benzoic acid and methanol. It is used in the fragrance industry and in the production of other benzoate esters (via transesterification). A technical-grade methyl benzoate is available as a by-product in the manufacture of dimethyl terephthalate [120-61 -6].
