• Synthesis and Nematocidal Activity of Hydroxystilbenes
  作者：Mohammad Ahad ALI、Kaoru KONDO、Yoshisuke TSUDA

  DOI：10.1248/cpb.40.1130

  日期：1992.5.25

  Various (E)-hydroxystilbenes were synthesized from (E)/(Z) mixtures of methoxystilbenes through a new (Z)-(E) isomerization method followed dy demethylation. The nematocidal activity appears when methoxystilbenes are demethylated to hydroxystilbenes. For this activity, a hydroxy group at the C-2 or C-3 position is necessary. Thus, 2-hydroxy-, 3-hydroxy-, 2, 6-dihydroxy-, 3, 4-dihydroxy-, 3, 5-dihydroxy-, 2, 2'-dihydroxy-, 3, 3'-dihydroxy-, 3, 4'-dihydroxy-, 2-hydroxy-4-methoxy-, 5-hydroxy-2-methoxy-, 2-hydroxy-6-methoxy-, 6-allyloxy-2-hydroxy-, 3-hydroxy-5-methoxy-, and 5-allyloxy-3-hydroxystilbenes showed rather potent nematocidal activity. The activity of 5-allyloxy-3-hydroxystilbene was the strongest [minimal lethal concentration (MLC)=30 μM]. The activities of the (E) and (Z) isomers were comparable. The activities were also retained, though they were weaker, in the dihydro derivatives, hydroxybibenzyls.

  通过一种新的(Z)-(E)异构化方法随后进行脱甲基反应，从(E)/(Z)混合甲氧基二苯乙烯中合成了多种(E)-羟基二苯乙烯。当甲氧基二苯乙烯脱甲基生成羟基二苯乙烯时，表现出杀线虫活性。为了产生这种活性，C-2或C-3位置上必须有一个羟基。因此，2-羟基-、3-羟基-、2,6-二羟基-、3,4-二羟基-、3,5-二羟基-、2,2'-二羟基-、3,3'-二羟基-、3,4'-二羟基-、2-羟基-4-甲氧基-、5-羟基-2-甲氧基-、2-羟基-6-甲氧基-、6-烯丙氧基-2-羟基-、3-羟基-5-甲氧基-和5-烯丙氧基-3-羟基二苯乙烯表现出相当强的杀线虫活性。5-烯丙氧基-3-羟基二苯乙烯的活性最强[最小致死浓度（MLC）=30 μM]。(E)和(Z)异构体的活性相当。二氢衍生物，羟基联苄中也保留了这些活性，尽管较弱。
• Efficient Heterogeneously Palladium-Catalysed Synthesis of Stilbenes and Bibenzyls
  作者：Giuseppe Cusati、Anja Wedig、Laurent Djakovitch

  日期：2009.1.1

  An alternative heterogeneously palladium catalysed procedure for the synthesis of functional stilbenes and bibenzyls is reported. Starting from aryl bromides and using simple commercially available Pd/C catalyst at a low catalytic rate (1 mol%), stilbenes are obtained with 30-100% GC-yields and bibenzyls are produced in a one-pot fashion with 27-100% GC-yields. The procedure showed, however, some limitations when applied to strongly deactivated aryl bromides that could be in some extent overcome by using corresponding iodo derivatives.

  报道了一种替代的异质钯催化程序，用于合成功能性斯蒂尔本和二苯乙烯。该方法以芳基溴化物为起始材料，使用简单的商用Pd/C催化剂，在低催化剂用量（1 mol%）下，斯蒂尔本的GC产率在30-100%之间，二苯乙烯则以单锅法生产，GC产率为27-100%。然而，该方法在强去活化的芳基溴化物应用时显示出一些局限性，但通过使用相应的碘衍生物可以在某种程度上克服这些问题。
