  Further Naphthylcombretastatins. An Investigation on the Role of the Naphthalene Moiety

  摘要：

  By synthesis and biological studies of new naphthalene analogues of combretastatins, we have found that the naphthalene is a good surrogate for the isovanillin moiety (3-hydroxy-4methoxyphenyl) of combretastatin A-4, always generating highly cytotoxic analogues when combined with the 3,4,5-trimethoxyphenyl or related systems. On the other hand, when the naphthalene replaces the 3,4,5-trimethoxyphenyl moiety, the cytotoxic activity is largely decreased. The most cytotoxic naphthalene analogues of combretastatins, which also produce inhibition of tubulin polymerization, exerted their antimitotic effects through microtubule network disruption and subsequent G(2)/M arrest of the cell cycle in human cancer cells.

• Olefination with Sulfonyl Halides and Esters: <i>E</i> -Selective Synthesis of Alkenes from Semistabilized Carbanion Precursors

  Sulfur‐based olefination with Horner–Wadsworth–Emmons‐type mechanism is systematically studied. Nonstabilized and semistabilized carbanion precursors react with carbonyl compounds giving good yields of olefins, and for the latter reagents E isomers of alkenes predominate.

  系统地研究了基于霍纳-沃兹沃思-埃蒙斯型机理的硫基烯烃化反应。未稳定的和半稳定的碳负离子前体与羰基化合物反应，可提供良好的烯烃收率，而对于后一种试剂，烯烃的E异构体占主导地位。
• Palladium-Catalyzed Dehydrative Heck Olefination of Secondary Aryl Alcohols in Ionic Liquids: Towards a Waste-Free Strategy for Tandem Synthesis of Stilbenoids

  All in one: A tandem strategy has been developed wherein secondary aryl alcohols are directly coupled with aryl halides to provide stilbenoids through a dehydrative Heck sequence in the ionic liquid [hmim]Br, and with water as a by‐product under microwave irradiation (see scheme). Classical methods do not permit this sequence to proceed in one pot, and some methods require multiple steps. hmim=1‐n

  总而言之：已开发了一种串联策略，其中仲芳基醇直接与芳基卤化物偶合，以通过离子液体[hmim] Br中的脱水Heck序列提供二苯乙烯类化合物，并在微波辐射下与水作为副产物（参见方案）。经典方法不允许此序列在一个锅中进行，并且某些方法需要多个步骤。hmim = 1 - n-己基-3-甲基咪唑鎓。
