SYNTHETIC INVESTIGATIONS IN THE FIELD OF ATTRACTIVE SUBSTANCES (SEX ATTRACTANTS) OF INSECTS XI. CONVENIENT SYNTHESIS OF NONADEC-cis-7-EN-11-ONE AND EICOS-cis-7-EN-11-ONE - COMPONENTS OF THE SEX PHEROMONE OF Carposina niponensis

A simple synthesis of the nonadec-cis-7-en-11-one and eicos-cis-7-en-11-one, components of the sex pheromone of the peach moth, has been performed from homopropargyl alcohols.

Heavier Carbonyl Olefination: The Sila-Wittig Reaction

The Wittig reaction is one of the most versatile tools in the repertoire of organic chemists. Thus, a broad variety of carbonyl compounds can be converted to tailor-made alkenes with phosphorus ylides under mild conditions. However, no comparable reaction has been reported for silanones, the silicon congeners of ketones. Here, we demonstrate for the first time the successful application of the Wittig olefination to iminosilylsilanone 1. The selective formation of a series of silenes (R2Sia? CR2) via the sila-Wittig reaction revealed an unprecedented approach to otherwise elusive compounds. In addition, the highly reactive and zwitterionic nature of 1 was also susceptible to nucleophilic attacks and cycloaddition reactions by and with the phosphorus ylides. Our results therefore make another important contribution to discovering the differences and similarities between carbon and silicon.

Provided is a method for preparing (E3,Z5)-3,5-alkadienyl acetate and (E3,Z5)-3,5-dodecadienyl acetate which is a sex pheromone of Brazilian apple leafminer. Specifically, provided is a method for preparing (E3,Z5)-3,5-alkadienyl acetate, comprising steps

Biocatalytic asymmetric and enantioconvergent hydrolysis of trisubstituted oxiranes

Asymmetric biohydrolysis of trialkyl oxiranes (±)-1a-3a using the epoxide hydrolase activity of whole bacterial cells proceeded in an enantioconvergent fashion and thus led to the corresponding (R)-configurated vicinal diols 1b-3b in up to 97% enantiomeric excess (e.e.) as the sole product. The mechanism of this enantioconvergence was investigated by 18O-labelling experiments and it was found that both enantiomers were hydrolysed with opposite regioselectivity.

Synthesis of 4,4-Disubstituted Cyclohexenones. Part 2. Cycloaddition of 2-Chloroacrylonitrile to 5-Substituted 1,3-Dimethoxycyclohexa-1,4-dienes

The cycloaddition of 2-chloroacrylonitrile to 1,3-dimethoxycyclohexadienes (3; R1=OMe, R2=H), derived by in situ conjugation of the Birch reduction products (12) produced from aromatic precursors (11) gave after acid work-up mainly bicyclooctanone

GLYCALS IN STEREOSPECIFIC SYNTHESIS. I. SYNTHESIS OF (+)-cis-DISPARLURE - THE SEX PHEROMONE OF THE GYPSY MOTH (Porthetria dispar L.)

An original approach to the synthesis of 2R,3S-epoxy-1-hydroxytridecane was developed on the basis of tri-O-acetyl-D-galactal.The product was used as the key synthon in the production of a sample of (+)-cis-disparlure with high optical purity.

NOUVELLE SYNTHESE DE TRIFLUOROMETHYLCETONES ET D' α-BROMO TRIFLUOROMETHYLCETONES

We report a new method for the preparation of trifluoromethylketones, as an alternative to the use of organometallics.The condensation of phosphonium ylides with trimethylsilyl trifluoroacetate provides silyloxy enol ethers whose hydrolysis leads to trifluoromethylketones.Bromation of the same silyloxy enol ether is also a convenient preparation of α-bromo trifluoromethylketone.
