The methyl ester of 3,7-dimethyl-8-hydroxyoctanoic acid have been prepared in good yields and with ee >98% by deprotonation of the starting trimethyl cyclooctanone 57, R = Me using (R,R) 3 and LiCl at — 78 °C (Scheme 37)77. This reaction is a key step in a versatile synthesis of optically active isoprenoid, which is present as a sub-unit in vitamins, plant metabolites, antibiotics and other naturally occurring compounds.

Metabolic pathways of menthol (137), menthone (149), thymol (179), and carvacrol methyl ether (202) are summarized in Figure 19.201. Menthol (137) is generally hydroxylated to give 1-hydroxy-(138), 2-hydroxy- (140), 4-hydroxy- (141), 6-hydroxy- (139), 7-hydroxy- (143), 8-hydroxy- (142), and 9-hydroxymenthol (144) and 1,8-dihydroxy- (146) and 7,8-dihydroxymenthol (148) (Asakawa et al., 1991 Takahashi et al., 1994 Van der Werf et al., 1997). Racemic menthyl acetate and menthyl chloroacetate are hydrolyzed asymmetrically by an esterase of microorganisms (Brit Patent, 1970 Moroe et al., 1971 Watanabe and Inagaki, 1977a,b). Menthone (149) is reductively metabolized to 137 and oxidatively metabolized to 3,7-dimethyl-6-hydroxyoctanoic acid (152), 3,7-dimethyl-... 

Figure 11.12. The tetrasaccharide sialyl Lewis. This bioactive oligosaccharide is found on the termini of glycolipids (one shown here as the methyl ester of 9-hydroxyoctanoic acid) and is believed to play an important role in cell-cell recognition.

Polyhydroxyalkanoates (PHAs) are polyesters of hydroxyacids (HAs) with the general structural formula as depicted in Figure 1 Where X varies from 600 to 35,000 n = 1 R = hydrogen Poly (3-hydroxypropionate) R = methyl Poly (3-hydroxybutyrate) R = ethyl Poly (3-hydroxyvalerate) R = propyl Poly (3-hydroxyhexanoate) R = pentyl Poly (3-hydroxyoctanoate) R = nonyl Poly (3-hydroxydodecanoate) n = 2 R = hydrogen Poly (4-hydroxybutyrate) n = 3 R = hydrogen Poly (5-hydroxyvalerate) (Ojumu et al., 2004).
