  摘要：

  在室温下仅2分钟的时间内，将2,4-二芳基-1,1,1-三氟丁-3-烯-2-烯烃及其TMS-醚在H 2 SO 4中定量环化成1-芳基-3-三氟甲基- 1 H-茚。该反应通过中间形成相应的CF 3-烯丙基阳离子进行，该中间体在最远离CF 3-基团的烯丙基碳原子上区域选择性地环化。将得到的CF 3-茚在EtOAc溶液中，在硅胶存在下，在室温下于4小时内定量异构化成3-芳基-1-三氟甲基-1 H-茚。

  Synthesis of chalcones via domino dehydrochlorination/Pd(OAc)2-catalyzed Heck reaction

  摘要：

  A new method has been developed for the cross-coupling of aryl halides with beta-chloroalkyl aryl ketones and their ester and amide analogs through a domino dehydrochlorination/Pd(OAc)(2)-catalyzed Heck reaction sequence. The enone intermediates generated in situ reduced the occurrence of side reactions and therefore enhanced the efficiency of the reaction. This reaction exhibited good tolerance to various functional groups on both substrates and provides rapid access to a wide range of chalcone derivatives.

  anti-oxidant properties. There are conflicting reports concerning the structural/electronic basis of the anti-oxidant activity of curcumin. Curcumin is a symmetrical diphenolic dienone. A series of enone analogues of curcumin were synthesized that included: (1) curcumin analogues that retained the 7-carbon spacer between the aryl rings; (2) curcumin analogues with a 5-carbon spacer; and (3) curcumin

  从香料姜黄获得的天然产物姜黄素（二氟甲酰甲烷，1,7-双（4-羟基-3-甲氧基苯基）-1,6-庚二烯-3,5-二酮）具有多种生物活性，包括抗癌，抗炎和抗血管生成活性。这些生物活性中的一些可能源自其抗氧化特性。关于姜黄素抗氧化活性的结构/电子基础的报道相互矛盾。姜黄素是对称的二酚二烯酮。合成了一系列姜黄素的烯酮类似物，包括：（1）保留在芳基环之间的7-碳间隔基的姜黄素类似物；（2）具有5碳间隔基的姜黄素类似物; （3）具有3个碳间隔基的姜黄素类似物（查耳酮）。这些系列包括保留或不包含酚基的成员。通过TRAP测定法和FRAP测定法测定抗氧化活性。大多数具有抗氧化活性的类似物保留了类似于姜黄素的酚环取代基。但是，许多没有酚取代基的类似物也是有活性的。这些非酚类类似物能够形成稳定的以碳为中心的叔基。

  It has been specifically shown to be an effective inhibitor of angiogenesis both in vitro and in vivo. Using curcumin as a lead compound for anti-angiogenic analog design, a series of structurally related compounds utilizing a substituted chalcone backbone have been synthesized and tested via an established SVR cell proliferation assay. The results have yielded a wide range of compounds that equal or

  An efficient one-pot synthesis of 1,2-dihydro-2-oxo-3-pyridinecarboxylate derivatives starting from enones and ethyl ­cyanoacetate in moderate to good yields is described. This novel tandem [3+3] annulation method mediated by FeCl3 involves Michael addition and ketone-nitrile annulation followed by aromatization-dehydrogenation. A plausible mechanism is also proposed.
