  Key structural features of cis-cinnamic acid as an allelochemical

  摘要：

  1-O-cis-cinnamoyl-beta-D-glucopyranose is one of the most potent allelochemicals isolated from Spiraea thunbergii Sieb. It is suggested that it derives its strong inhibitory activity from cis-cinnamic acid, which is crucial for phytotoxicity. It was synthesized to confirm its structure and bioactivity, and also a series of cis-cinnamic acid analogues were prepared to elucidate the key features of cis-cinnamic acid for lettuce root growth inhibition. The cis-cyclopropyl analogue showed potent inhibitory activity while the saturated and alkyne analogues proved to be inactive, demonstrating the importance of the as-double bond. Moreover, the aromatic ring could not be replaced with a saturated ring. However, the 1,3-dienylcyclo-hexene analogue showed strong activity. These results suggest that the geometry of the C-C double bond between the carboxyl group and the aromatic ring is essential for potent inhibitory activity. In addition, using several light sources, the photostability of the cinnamic acid derivatives and the role of the C-C double bond were also investigated. (c) 2012 Elsevier Ltd. All rights reserved.

  Tosylhydrazones derived from aryl aldehydes react with t-BuOK, ClFeTPP, (MeO)3P, and aldehydes to furnish olefins with high E selectivity. These reactions occur through a Wittig-type pathway via the corresponding diazo compounds, metal carbenes and phosphorous ylides, with the water-soluble trimethyl phosphate as the byproduct. Similar reactions can also be performed using ethyl diazoacetate; however

  源自芳基醛的甲苯磺酰腙与 t-BuOK、ClFeTPP、(MeO)3P 和醛反应以提供具有高 E 选择性的烯烃。这些反应通过相应的重氮化合物、金属卡宾和磷叶立德通过 Wittig 型途径发生，副产物为水溶性磷酸三甲酯。使用重氮乙酸乙酯也可以进行类似的反应；然而，仅在 LiBr 存在下才观察到高 E 选择性。在这种情况下，该反应被认为是通过通过 Arbuzov 反应形成的膦酸阴离子发生的。因此，该烯化反应通过 Horner-Wadsworth-Emmons (HWE) 反应发生，但膦酸阴离子是在完全无碱的条件下生成的。

  serves as an effective promoter for the room-temperature stereoselective synthesis of α,β-unsaturated esters, fluorides, and nitriles from a wide array of aromatic, aliphatic, heterocyclic, and cyclic aldehydes and ketones, using a range of Wadsworth−Emmons (WE) phosphonates. Among the analogues of 1c [R = Me (1a), i-Pr (1b), Bn (1d)], 1a and 1b performed well, although longer reaction times were involved

  双环三氨基膦P（RNCH 2 CH 2）3 N（R = i -Bu，1c）可作为室温下立体选择性合成α，β-不饱和酯，氟化物和腈的有效促进剂芳香族，脂肪族，杂环和环状醛和酮，使用一系列Wadsworth-Emmons（WE）膦酸酯。在1c [R = Me（1a），i -Pr（1b），Bn（1d）]的类似物中，1a和1b表现良好，尽管涉及的反应时间更长，而1d导致的收率低于1c。氰基，氯，溴，甲氧基，氨基，酯和硝基等官能团的耐受性很好。我们能够分离和表征（通过X射线；见上文）由2b和1c形成的反应性WE中间体。

  A practical, efficient, and mild process is described for the synthesis of unsaturated esters from aldehydes in good yields and diastereoselectivities. All of the reagents used in the protocol are commercially available at a nominal price: N2CHCO2Et, catalytic (1 mol%) ReOCl3(PPh3)2, and (EtO)3P. Additionally, the reaction process can be carried out successfully in good yields (85%) and diastereoselectivities

  The commercially available Fe(III) and Ru(II) porphyrin complexes Fe(TPP)Cl and Ru(TPP)(CO) are efficient catalysts for selective olefination of a variety of aldehydes with ethyl diazoacetate in the presence of triphenylphosphine. The reactions were carried out under mild conditions in a one-pot fashion with the use of a stoichiometrical amount of EDA, which proceeded with excellent yields and high

  Peterson adducts have been known to stereospecifically give syn-elimination products upon treatment with base except when the product olefin is in conjugation with an electron-withdrawing group. The missing piece has been put in place by using a catalytic amount of DBU, by which syn-elimination could be effected to provide the thermally less stable Z-olefin from the anti-adduct with high selectivity

  已知彼得森加合物在用碱处理后立体定向地产生顺式消除产物，除非产物烯烃与吸电子基团共轭。缺失的部分已经通过使用催化量的 DBU 就位，通过它可以实现合成消除，以高选择性从抗加合物中提供热稳定性较差的 Z-烯烃。
