Phenyl amyl alcohol

Of these phenyl-amyl alcohol has a pleasant, but somewhat evanescent lemon-like odour phenyl-hexyl alcohol has a very similar odour to this and phenyl-heptyl alcohol has a slight, but extremely agreeable odour [Pg.129]

In detergent perfumes, the stabiUty of vanillin is not always certain. It depends on the association made with other raw materials, eg, with patchouli, frankincense, cloves, most of the animal notes, and such chemicals as amyl saUcylate, methyl ionones, heflotropin, gamma undecalactone, linalool, methyl anthrarulate, benzyl acetate, phenyl ethyl alcohol, cedar wood derivatives, oak mosses, coumarin, benzoin. Pern balsam, and cistus derivatives. In some cases, these mixtures can cause discoloration effects.

A vial containing ( )-4-phenyl-3-butyn-2-ol (73.0 mg, 0.500 mmol) and catalyst 16 (3.3 mg, 0.005 mmol) in tert-amyl alcohol (1.0 mL) was capped with a septum and sonicated to help dissolve the catalyst. The resulting purple solution was cooled to 0 °C, and Ac O (35.4 pL, 0.375 mmol) was added by syringe. After 49 h, the reaction mixture was quenched by the addition of a large excess of MeOH. After concentration in vacuo, the residue was purified by FC on sihca gel (EtOAc/hexanes, 1/9 — 1/1 then EtOAc/hexanes/ EtjN, 9/9/2) to afford the (l )-acetate (68.6% ee by chiral-GC) and the (5)-alcohol (96.0%ee by chiral-GC on the acetate obtained following esterification). The calculated selectivity value at 58.3% conversion was s = 20.2. 

Deamination 17 Examples of deamination and decarboxylation include conversion of amino acids to fusel oil (leucine to isoamyl alcohol, isoleucine to amyl alcohol, and phenylalanine to phenyl ethanol). Fusel oil formation is a normal function of all yeast fermentations (in alcoholic beverages, levels range from trace to 2200 parts per million). Deamination Glutamic acid to gamma-OH-butyric acid (S. cerevisiae).

A mixture 31.3 g of o-chlorobenzoic acid, 32.2 g of trifluoromethyl-m-aminobenzene, 3 g of copper powder, 13.8 g of waterless potassium carbonate and 100 ml amyl alcohol was refluxed for 4 hours. To the cooled mixture was added 25 ml of 10 N solution NaOH and the mixture was concentrated and filtrated. Addition to the filtrate hydrochloric acid and water give a sediment of 2-((3-trifluromethyl)phenyl)aminobenzoic acid. After recrystallization from hexane 2-((3-trifluromethyl)phenyl)aminobenzoic acid have melting point 134-136°C. 

Enzyme assays were conducted in a 10 mL screw-neck glass test tube containing 100 fiL of lysate, 90 fiL of a 250 /ng/mL solution of 6-mercaptopurine in 0.01 M HC1, and 15 /uL of 250 mM sodium phosphate buffer (pH 9.2). Reactions were initiated by the addition of 32 fiL of a 3 1 mixture of 250 fiM S-adenosyl-L-methionine and 30 mM dithiothreitol. The final pH was 7.5. After a 1-hour incubation at 37°C, the reaction was stopped by the addition of 850 fjL of ice-cold 3.5 mM dithiothreitol and 50 fih of 1.5 M H2S04. The tubes were then heated at 100°C for 2 hours. To each tube, 500 fiL of 3.4 M NaOH was added, immediately followed by 8 mL of toluene-amyl alcohol-phenyl mercuric acetate. The tubes were shaken for 10 minutes and centrifuged. Then 6 mL of the toluene layer was transferred to a glass-stoppered conical test tube and 0.2 mL of 0.1 M HC1 added. After vortex-mixing and centrifuging, the toluene layer was discarded. Samples (50 fiL in 0.1 M HC1) were used for HPLC analysis. Product formation was linear for up to 120 minutes and 150 /u,L of lysate. 

Hexahydronicotinic acid (90%) is obtained by catalytic hydrogenation of nicotinic acid at 3 atm. pressure over colloidal platinum. Preparation of the catalyst is described. The 9,10 double bond in the acridine nucleus is reduced at 10° by sodium amalgam in dilute sodium carbonate solution to give 9,10-dihydroacridine-S>-carboxylic acid in 70% yield. 2-Phenyl-cyclohexanecarboxylic acid (96%) is prepared by the selective reduction, of 2-phenylbenzoic acid by a large excess of sodium in refluxing amyl alcohol. ... 

Hydrolysis of a-phenyl-j8-methylbutyronitrile (p. 252) by the above procedure gives the amide, m.p. 111-112°. In order to complete hydrolysis of the acid, a mixture of 10 g. (0.063 mole) of the nitrile, 20 g. (0.35 mole) of potassium hydroxide, and 50 g. of amyl alcohol is refluxed for 6 hours. Work-up of the reaction mixture as described above gives a-phenyl- -methylbutyric acid, m.p. 61-62°.

The volatile compounds quantified were acetaldehyde, ethyl acetate, methanol, 1-propanol, isobutanol, amyl alcohols, isobutanol, ethyl valerate, ethyl lactate, ethyl caprylate, ethyl caproate, 2-furfuraldehyde and 2-phenyl ethanol (figure 3). Two yeasts isolated from fermentation stage in the mezcal processes were used to evaluate the volatile production in different agave juice species (table 5 and table 6). Both yeasts are Kluyoeromyces marxianus and the volatile compoxmds were produced at different levels, those results show the importance to select the yeast used in the process.
