Biosynthesis of α- and β-ionone, prominent scent compounds, in flowers of Osmanthus fragrans.
Acta Biochim. Pol. 59(1) , 79-81, (2012) Carotenoid derived volatiles are important fragrance compounds, which contribute to the scents of flowers from diverse taxa. A famous example is represented by the flowers of Osmanthus fragrans where apocarotenoids account for more than 20% of all volatiles. ... |

CYP264B1 from Sorangium cellulosum So ce56: a fascinating norisoprenoid and sesquiterpene hydroxylase.
Appl. Microbiol. Biotechnol. 95(1) , 123-33, (2012) Many terpenes and terpenoid compounds are known as bioactive substances with desirable fragrance and medicinal activities. Modification of such compounds to yield new derivatives with desired properties is particularly attractive. Cytochrome P450 monooxygenas... |

New attractants for males of the solanaceous fruit fly Bactrocera latifrons.
J. Chem. Ecol. 34(12) , 1532-5, (2008) alpha-Ionone, alpha-ionol, and their mixtures with phenolic volatiles act as potential male lures for the solanaceous fruit fly Bactrocera latifrons (Hendel). However, the attractiveness of these compounds is not as strong as that of other well-known tephriti... |

Stereo- and regioselective hydroxylation of alpha-ionone by Streptomyces strains.
Appl. Environ. Microbiol. 64(10) , 3878-81, (1998) A total of 215 Streptomyces strains were screened for their capacity to regio- and stereoselectively hydroxylate beta- and/or alpha-ionone to the respective 3-hydroxy derivatives. With beta-ionone as the substrate, 15 strains showed little conversion to 4-hyd... |

Enhancement of attraction of alpha-ionol to male Bactrocera latifrons (Diptera: Tephritidae) by addition of a synergist, cade oil.
J. Econ. Entomol. 94(1) , 39-46, (2001) Male lures are known for many tephritid fruit fly species and are often preferred over food bait based traps for detection trapping because of their high specificity and ability to attract flies over a wide area. Alpha-ionol has been identified as a male lure... |

Efficient terpene hydroxylation catalysts based upon P450 enzymes derived from actinomycetes.
Org. Biomol. Chem. 3(16) , 2930-4, (2005) The hydroxylation of alpha-ionone 1 and beta-ionone 2 to their corresponding mono-hydroxylated derivatives has been examined using a recombinant E. coli whole cell system, in which cytochromes P450 SU1 and SU2, and P450 SOY were over-expressed with their cogn... |

Enantioselective synthesis and olfactory evaluation of 13-alkyl-substituted alpha-ionones.
Chem. Biodivers. 5(6) , 1045-57, (2008) To study the influence of the steric bulk of the substituents at C(5) on the olfactory characteristics of alpha-ionone, the (S)-antipodes of compounds 8-10 were synthesized starting from (S)-alpha-cyclogeraniol (14a). The latter was available in useful prepar... |

Investigation of binding behavior of alpha- and beta-ionones to beta-lactoglobulin at different pH values using a diffusion-based NOE pumping technique.
J. Agric. Food Chem. 51(7) , 1988-93, (2003) Diffusion-based NMR techniques were employed to study effects of pH on beta-lactoglobulin (BLG) conformation and binding affinity to alpha- and beta-ionone. In the first part of the study, the influence of pH on the diffusion coefficient of BLG in D(2)O solut... |

Active ingredients in cade oil that synergize attractiveness of alpha-ionol to male Bactrocera latifrons (Diptera: Tephritidae).
J. Econ. Entomol. 97(3) , 862-70, (2004) Cade oil, a commercially available essential oil produced by destructive distillation of juniper, Juniperus oxycedrus L., twigs, is known to synergize the attractancy of alpha-ionol to male Bactrocera latifrons (Hendel). Through chemical fractionation and out... |

Expedient construction of the Ziegler intermediate useful for the synthesis of forskolin via consecutive rearrangements.
Org. Lett. 11(23) , 5442-4, (2009) The Ziegler intermediate, useful for the total synthesis of forskolin, was synthesized in 10 reaction steps starting from commercially available alpha-ionone. This highly efficient synthesis relies on the success of two consecutive highly regio- and stereosel... |
