  The present invention relates to metathesis syntheses for insect sex-attractant pheromones or their components, such as E-5-decenyl acetate, the major component of the Peach Twig Borer pheromone; (5R, 6S)-6-acetoxy-5-hexadecanolide, the mosquito oviposition attractant pheromone; E9, Z11-hexadecadienal, the pecan nut casebearer moth pheromone; 9-tetradecenyl formate, an analog of the Diamondback Moth (DBM) pheromone; 11-tetradecenyl acetate, the Omnivorous Leafroller (OLR) pheromone; E-4-tridecenyl acetate, the major component of the Tomato Pinworm (TPW) pheromone; E,E-8,10-dodecadienol, the Codling Moth (CM) pheromone. The syntheses preferably employ a Class I-IV metathesis catalyst, entail few reaction steps, use generally commercially available starting materials, and have relatively short process times. These syntheses produce good yields without the need for expensive or sophisticated equipment. The invention also provides an inexpensive route for producing omega-haloalkenols by cross-metathesizing alpha-omega-diacetoxy alkenes and alpha-omega-dihalides to yield omega-haloalkenols, which are easily converted into omega-haloalkanols under traditional hydrogenation methods.

  本发明涉及对昆虫性诱素或其组分进行交换合成，如E-5-癸烯醇醋酸酯，桃枝蠕蛾性信息素的主要成分；（5R, 6S）-6-乙酰氧基-5-十六醇内酯，蚊子产卵引诱素；E9, Z11-癸二烯醛，山核桃果蛾性信息素；9-十四烯酸甲酯，菜青虫性信息素的类似物；11-十四烯醇醋酸酯，杂食卷叶蛾性信息素；E-4-十三烯醇醋酸酯，番茄针孔螟性信息素的主要成分；E,E-8,10-十二二烯醇，苹果蛾性信息素。这些合成通常采用I-IV类交换催化剂，步骤较少，使用通常易得的起始物质，并具有相对较短的工艺时间。这些合成产量良好，无需昂贵或复杂的设备。该发明还提供了通过交叉交换α-Ω-二乙酰基烯烃和α-Ω-二卤代烃来产生Ω-卤代烯醇的廉价途径，后者可以在传统的氢化方法下轻松转化为Ω-卤代烷醇。
• Electrochemical oxidation of acylsilanes and their tosylhydrazones

  Oxidation potentials of acylsilanes were found to be much less positive than those of ketones and aldehydes. The effect of silicon is attributed to the rise of the HOMO level by the interaction between the C-Si sigma-orbital and the nonbonding p orbital of the carbonyl oxygen which in turn favors the electron transfer. Preparative electrochemical oxidation of acylsilanes proceeded smoothly, giving rise to facile cleavage of the C-Si bond and the introduction of nucleophiles such as alcohols, water, and carbamates onto the carbonyl carbon. Electrochemical properties of tosylhydrazones of acylsilanes were also investigated. A decrease in oxidation potential of tosylhydrazones caused by silyl substitution was found to be smaller than that for carbonyl compounds. Preparative electrochemical oxidation of tosylhydrazones of acylsilanes gave the corresponding nitriles with consumption of a catalytic amount of electricity.

• Enzymes in organic synthesis. 27. Lipase-Catalyzed Synthesis of (5R,6S)-6-Acetoxyalkan-5-olides - homologues of the mosquito oviposition attractant pheromone
  作者：B. Henkel、A. Kunath、Hans Schick

  DOI：10.1002/prac.19973390176

  日期：——

  Sixteen homologous (5R*,6S*)-6-hydroxyalkan-5-olides rac-5 and their acetoxy derivatives rac-6 were synthesized from the corresponding methyl (Z)-alk-5-enoates 3 by osmium(VIII) oxide catalyzed cis-hydroxylation to the dihydroxy esters rac-4 and hydrolysis of these esters followed by lactonization. Pancreatin-catalyzed lactonization of the dihydroxy esters rac-4 afforded enantiomerically enriched hydroxy lactones ent-5, five of which were obtained enantiomerically pure by recrystallization. Acetylation of the 6-hydroxyalkan-5-olides rac-5 by vinyl acetate catalyzed by the lipase SP 526 provided enantiomerically enriched 6-acetoxyalkan-5-olides 6 with an enantiomeric excess of more than 90% in nine cases. These compounds are known as mosquito oviposition attractant pheromone (6h) or its homologues.
