摘要:This invention provides improved biological synthesis of the apocarotenoid α-ionone in Saccharomyces cerevisiae. The final native step involved in the natural apocarotenoid pathway depends on an endogenous farnesyl pyrophosphate synthase (FPPs). From there, heterologous geranylgeranyl pyrophosphate synthase (crtE), phytoene synthase (crtB), phytoene desaturase (crtI), lycopene ε-cyclase (LycE) and a Carotenoid Cleavage Dioxygenase (CCD1) are required to complete the synthesis of α-ionone. Lycopene ε-cyclase from lettuce (Lactuca sativa) or modified cyclase from Arabidopsis thaliana was used to overproduce lycopene which was then cleaved by the carotenoid cleavage dioxygenase from Petunia hybrida (Ph-CCD1).

摘要:Described is a process for preparing triconjugated dienones defined according to the structure: wherein R1 represents C1-C8 alkyl, phenyl or phenyl methyl and wherein R2 represents hydrogen or C1-C5 lower alkyl; and wherein the wavy lines are indicative of a 'cis' or a 'trans' juxtaposition of the R2, methyl, acyl or vinyl moieties about one or both of the carbon-carbon double bonds which process involves the reaction of an acyl halide having the structure: (wherein X represents chloro) with a substituted or unsubstituted prenyl ester having the structure: wherein R3 represents C1-C5 alkyl in the presence of an aluminum chloride catalyst and a methylene dichloride solvent in order to form the novel intermediate genus defined according to the structure: then dehydrohalogenating the compound defined according to the structure: using an alkali metal carbonate and a dimethylformamide solvent in order to form the novel compound genus having the structure: wherein one of the dashed lines represents a carbon-carbon double bond and the other of the dashed lines represents a carbon-carbon single bond; and then dehydroacyloxylating the compound having the structure: in order to form the compound having the structure: the dehydroacyloxylation step taking place in the presence of an alkali metal carbonate and dimethylformamide solvent.
