  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.

  新的维蒂希试剂的制备及其在α，β-不饱和膦酸酯的合成中的应用。

  摘要：

  通过用三苯基膦处理三氟甲磺酸（二乙氧基膦基）甲基三氟甲磺酸盐，已通过其三氟甲磺酸盐（4a）首次成功合成了Wittig试剂[（二乙氧基膦基）亚甲基]三苯基膦烷（1b）。该方法已应用于其他phosphor烷和phospho盐的合成。这样合成的新的Wittig试剂用各种醛和活化的酮处理，得到相应的α，β-不饱和膦酸酯。三苯基膦1b和三苯基4 4a导致顺式和反式异构体均以顺式为主，而当使用三丁基试剂（1c和4d）时，反式异构体几乎全部形成。

  An efficient and stereoselective procedure for the preparation of E-1-alkenylphosphonates by copper-mediated cross-coupling between 1,1-dibromo-1-alkenes and dialkyl phosphites is reported. The reaction allows for formal substitution of both bromine atoms, respectively, by an hydrogen and a dialkoxyphosphoryl.
