Synthesis of mono- and sesquiterpenoids; XXIII. Synthesis of (E)-endo-Bergamoten-12-oic acids (α-form, β-form), moth oviposition stimulants isolated from wild tomato leaves

(E)-endo-Bergamoten-12-oic acids (α-form: 1, β-form: 2), moth oviposition stimulants isolated from wild tomato leaves, were synthesized starting from the lactone 7.

APPLICATION OF BIOCHEMICAL METHODS IN ENANTIOSELECTIVE SYNTHESIS OF BIOACTIVE NATURAL PRODUCTS

Enzymes as well as yeasts were used in enantioselective syntheses of bioregulators such as hormones and semiochemicals.Lipases and esterases were employed in achieving optical resolution, conversion of meso-compounds to optically active compounds, and macrolactonization.Lactase effected glucosidation of a phenolic hydroxy ketone without any protection of the functional groups.Yeasts provided a variety of optically active hydroxy esters and ketones, which served as versatile non-racemic chiral building blocks.
