标题:Enantio-And Diastereoselective Protonation Of Photodienols: Total Synthesis Of (R)-(-)-Lavandulol
摘要:The Total Synthesis Of (R)-(-)-Lavandulol 1 Has Been Achieved By Asymmetric Protonation Of Photodienols Obtained From The Irradiation Of Prochiral Alpha,Beta-Unsaturated Esters. The Photodeconjugation Of Ethyl 5-Methyl-2-(1'-Methylethylidene)-4-Hexenoate (3A),Carried Out In The Presence Of Catalytic Amounts Of A Beta-Amino Alcohol Prepared From (+)-Camphor,Gives The Beta,Gamma-Unsaturated Isomer 2A In Good Yields But With Moderate Enantioselectivities (40% Ee). In Contrast,Irradiation Of The Corresponding Ester 3B,Bearing The 1,2:5,6-Di-O-Isopropylidene-D-Glucose Group As A Chiral Alkoxy Moiety,Affords The Deconjugated Product 2B In High De (>95%). Simple Reduction Of The Ester Function With Lialh4 Gives (R)-(-)-Lavandulol (1) Without Loss Of Optical Purity.

标 题:Synthesis of the Grape Mealybug Pheromone trans-alpha-Necrodyl Isobutyrate
发明人：CHEBNY VINCENT JAMES
权利人:TRECE INC
摘要:Methods are provided for synthesizing the grape mealybug pheromone, trans-α-necrodyl isobutyrate, starting with essential plant oils that contain trans-α-necrodyl acetate. The synthesis method, in two steps, converts the trans-α-necrodyl acetate to trans-α-necrodol and then converts the trans-α-necrodol to the desired trans-α-necrodyl isobutyrate. The first step can be achieved by either of a hydrolysis reaction or a reduction reaction. In the hydrolysis reaction, the essential oil is mixed in an alcohol solvent with a hydroxide base, or by mixing the essential oil in an aqueous acid. A reduction reaction can instead by performed in an organic solvent in the presence of a reducing agent. The trans-α-necrodol is converted to the desired trans-α-necrodyl isobutyrate by an esterification reaction with a carboxylic acid, an acyl halide, or an acid anhydride.

标题:Manufacture of γ,δ-unsaturated ketones
发明人：VON FRAUNBERG KARL
权利人:BASF AG
摘要:gamma , delta -Unsaturated non-cyclic aliphatic ketones are prepared by reacting specific alpha , beta -unsaturated ketones with vinylmagnesium halide in the presence of inorganic copper compounds at temperatures below 0 DEG C. The reaction products are valuable intermediates in the synthesis of a number of perfumes. For example, the compound 3,3-dimethyl-1-hexen-5-one which may be prepared from mesityl oxide and vinylmagnesium chloride is an intermediate for lavandulyl compounds such as lavandulol and lavandulyl acetate.

摘要:The present invention relates to an inhibitor for tobacco axillary bud growth, the inhibitor comprising, as an active ingredient, one or more kinds of very-long chain fatty acid synthesis inhibitors such as a chloroacetamide-based herbicide, fentrazamide, cafenstrole or indanofan; an inhibitor for tobacco axillary bud growth, the inhibitor comprising the aforesaid very-long chain fatty acid synthesis inhibitor together with clorthal-dimethyl or an aliphatic alcohol having 6 to 20 carbon atoms; and a method for inhibiting tobacco axillary bud growth which comprises applying the inhibitor for tobacco axillary bud growth. The inhibitor for tobacco axillary bud growth of the present invention shows sustained drug efficacy at a low concentration, induces neither chemical injury nor disease, and can contribute to the improvement in labor productivity.
