By the action of tropinone reductase I (TR I) and tropinone reductase II (TR II), tropinone (6) is reduced to tropine (10) and pseudotropine (11), respectively [20-23] (Scheme 12.3). The correlation between the two enzymes is essential for the diversity of the alkaloid spectrum of the plants producing 3-monosubstituted, 3,6- or 3,7-disubstituted, 3-substituted-6,7-epoxy- and 3,6,7-trisubstituted tropane alkaloids, respectively [24, 25]. It is determined that TR I is dominant for the species of family Solanaceae therefore, the alkaloids of a-series, derived from tropine, are prevailing [26]. It is established the configuration of the substituents at C-6 and C-7 is always p- [27]. The obtained tropine (10) and pseudotropine (11) further is esterified with various aliphatic and aromatic carboxylic acids such as tropic, apotropic, tiglic, propionic, butyric, isobutyric, and other acids [19].

The biosynthesis of the insect juvenile hormone (19) continues to present incorporation problems. The acid 10-epoxy-7-ethyl-3,ll-dimethyltrideca-2,6-dienoic acid (20) acts as a substrate for the hormone in the giant silk moth, Hyalopkora cecropia. L-Methionine gave the ester methyl group. However, it did not contribute to the carbon skeleton whilst farnesol, farnesol pyrophosphate, propionate, and mevalonate were apparently not utilized for the biosynthesis of the hormone under the conditions of these experiments. There was a very low incorporation of [2- C]acetate into juvenile hormone. [Pg.7]
