  • Structural Elucidation of Twelve Novel Esters Composed of Five Fatty Acids and Three New Branched Alcohols Together with Four Monoterpenoids from Sancassania shanghaiensis (Acari: Acaridae)
    作者:Tomoyo SAKATA、Kimiko OKABE、Yasumasa KUWAHARA
    DOI:10.1271/bbb.65.919
    日期:2001.1
    A total of 12 novel esters and four monoterpenoids (rosefuran, (2R,3R)-epoxyneral, and α- and β-acaridials) were detected by GC/MS analyses as the opisthonotal gland components of Sancassania shanghaiensis. The acidic fraction after hydrolysis was composed of five common fatty acids (palmitic, stearic, oleic, linoleic and arachidic acid), while the alcoholic fraction consisted of two major components (C6 and C8 alcohols with branched methyls), together with a trace amount of C9 alcohol. The Two major alcohols were identified as new alcohols [(S)-2-methylpentanol and (2S,4S)-2,4-dimethylhexanol] by comparing the physico-chemical data of their 3,5-dinitrobenzoates with those of regio-selectively synthesized alcohols. The C9 alcohol was suggested as (2S,4S)-2,4-dimethylheptanol, based on a structural and biogenetic analogy to the C6 and C8 alcohols. Five of the compounds were each identified by GC to be (S)-2-methylpentyl esters from five fatty acids, and the other five components likewise as (2S,4S)-2,4-dimethylhexyl esters. The remaining two were suggested as (2S,4S)-2,4-dimethylheptyl Stearate and linolate.
    GC/MS分析在Sancassania shanghaiensis的抱粉腺成分中检测到总共12种新型酯和4种单萜(玫瑰呋喃、(2R,3R)-环氧橙花醇以及α-和β-刺檗二醇)。经过水解后的酸性部分由5种常见脂肪酸(棕榈酸、硬脂酸、油酸、亚油酸和花生酸)组成,而醇性部分则主要由两种成分(带有支链甲基的C6和C8醇)组成,同时含有微量的C9醇。通过比较其3,5-二硝基苯甲酸酯的物理化学数据与选择性合成醇的数据,确认这两种主要醇为新型醇[(S)-2-甲基戊醇和(2S,4S)-2,4-二甲基己醇]。根据结构和生物学上的相似性,C9醇被推测为(2S,4S)-2,4-二甲基庚醇。通过GC鉴定,五种化合物分别为五种脂肪酸的(S)-2-甲基戊酯,另外五种成分同样为(2S,4S)-2,4-二甲基己酯。剩下的两种被推测为(2S,4S)-2,4-二甲基庚酯的硬脂酸酯和亚油酸酯。
  • A new synthesis of serricornin [(4s,6s,7s)-7-hydroxy-4,6-dimethyl-3-nonanone], the sex pheromone of the cigarette beetle
    作者:Kenji Mori、Hidenori Watanabe

    日期:1985.1
    Serricornin, the sex pheromone of Lasioderma serricorne F, was synthesised in 7.6% overall yield starting from methyl (R)-3-hydroxypentanoate of microbial origin. Its (4R,6S,7S)-isomer was also synthesised.

  • Regioselective Carbonylation of <i>trans</i>-Disubstituted Epoxides to β-Lactones: A Viable Entry into <i>syn</i>-Aldol-Type Products

    reported for the regioselective carbonylation of trans-disubstituted epoxides to cis-β-lactones. The two catalysts display high and opposing selectivities, which generally are difficult to achieve for this class of epoxides. The resulting β-lactones are well-defined precursors for a wide variety of aldol-type compounds. Altogether, carbonylation of disubstituted epoxides is established as a viable and
    据报道,两种新催化剂可用于将反式双取代环氧化物区域选择性羰基化成顺式-β-内酯。这两种催化剂显示出高且相反的选择性,这对于此类环氧化物通常难以实现。由此产生的 β-内酯是各种羟醛型化合物的明确前体。总之,双取代环氧化物的羰基化被确立为合成和抗羟醛产品的可行且经济的入口。

Hydride deliveries to different acyclic substrates and calculations also suggest that the higher anti‐selectivities obtained with borinate intermediates are not related to the formation of a complex mimicking an exocycle. From a broader standpoint, this study reveals important conformational factors for reactions taking place at a center vicinal to a heterocycle or an α‐alkoxy
    将带有杂环exo(α)的卤代前体自由基还原为以碳为中心的自由基,会增强抗选择性,这种现象我们称为“环外效应”。在BHandHLYP / TZVP级别的新实验数据和DFT计算表明,环外效应的起源与自由基中间体在过渡态(ΔE ≠应变)达到其反应构象所需的应变能有关。此外,受约束的THP系统的自由基减少表明,较高的2,3-抗只有当自由基链处于赤道取向时,才能达到诱导作用。氢化物可递送至不同的非环状底物,并且计算结果还表明,硼酸盐中间体可获得更高的抗选择性,与模拟环外化合物的复合物的形成无关。从更广泛的角度来看,这项研究揭示了重要的构象因子,这些构象是在中心邻位发生的对杂环或α-烷氧基的反应。

    and Ralstonia sp. (RasADH) could also accept bulkier keto esters (‘bulkybulkysubstrates). SyADH also provided preferentially syn‐(2R,3S) isomers and RasADH showed in some cases good selectivity towards the formation of anti‐(2S,3S) derivatives. With anti‐Prelog ADHs such as LBADH from L. brevis or LKADH from L. kefir, syn‐(2S,3R) alcohols were obtained with high conversions and diastereomeric excess
