  Synthesis and Herbicidal Activity of Substituted Tetrahydronaphthalenes (Part II)

  摘要：

  This paper reports the synthesis and the biological activity of novel tetrahydronaphthalenes with substitution of functional groups at each position of the aromatic ring and substitution of various alkyl groups at the 1-position of the non-aromatic ring. These compounds exhibited pre-emergent herbicidal activity which was determined by the orientation and type of functional groups on the aromatic ring with the 1,1-dimethyl substitution on the non-aromatic ring. The activity tended to be highest for nitro or methyl at the 5- and 7-positions with an amino or ester group at the 6-position and a dimethyl substitution at the 1-position.

  derivatives as single diastereoisomers in most cases. The position of the substituents was also of crucial influence on the outcome; in several cases ipso-substitution leading to the formation of spiro compounds was observed. Electron-donating substituents at the aromatic moiety are less favourable for the ketyl–aryl couplings. They apparently impede the second electron transfer that is involved in this multi-step

  这项综合研究描述了芳基部分的取代基对 SmI2 介导的分子内酮基-芳基偶联反应的影响。不同取代的γ-芳基酮被用作前体，其通过4-戊烯-2-醇与相应的溴苯或碘苯的Heck反应直接制备。在用两当量的二碘化钐γ-芳基酮处理后，带有吸电子取代基，如氰基、三氟甲基或羰基，在大多数情况下，得到预期的六氢化萘衍生物，为单一的非对映异构体。取代基的位置对结果也有至关重要的影响。在一些情况下，观察到导致形成螺环化合物的 ipso 取代。芳族部分的给电子取代基对酮基-芳基偶联不太有利。它们显然阻碍了这个多步骤过程中涉及的第二次电子转移。在这些观察的基础上，详细讨论了 SmI2 促进的酮基-芳基偶联的机制。对于在间位具有吸电子取代基的前体，SmI2 促进的环化的相当稳定的碳负离子中间体可以用丙酮或烯丙基溴作为亲电试剂捕获，以区域选择性地提供相应的加成产物。我们的结果对于立体选择性生成的六氢化萘衍生物的合成应用应该是有价值的。（©
