摘要:一种新的磁性可分离催化剂被制备,该催化剂由二核mn(II)络合物[mn₂(Hl)₂(H₂o)₄]组成,其中hl = 2-[(2-羟基苄叉)-氨基]-3-(4-羟基苯基)-丙酸,支持在功能化的(3-氯丙基)-三甲氧基硅烷(Cptms)涂层磁性纳米颗粒(Mnps)上.合成的催化剂通过多种物理化学和光谱方法进行了表征.结果表明,该固定化复合物在使用过氧化氢(H₂o₂)作为氧化剂的情况下,对不同的硫化物和烃的氧化反应表现出非常好的异相催化活性.催化剂可以通过简单的磁分离方法轻易回收,并且可以重复使用多次,而催化活性几乎没有显著损失.

摘要:The invention provides methods for the synthesis of a halichondrin macrolides through a macrocyclization strategy. The macrocyclization strategy of the present invention involves subjecting a non-macrocyclic intermediate to a carbon-carbon bond-forming reaction (e.g., an olefination reaction (e.g., Horner-Wadsworth-Emmons olefination), catalytic Ring-Closing Olefin Metathesis, or Nozaki-Hiyama-Kishi reaction) to afford a macrocyclic macrolide. The invention also provides compounds useful as intermediates in the synthesis of a halichondrin macrolides and methods for preparing the same.

摘要:Disclosed are ultrafast flow synthesis of functionalized sulfonyl fluorides and subsequent SuFEx connections via lithiated chemistry. In detail, a method of synthesizing an ortho-functionalized benzenesulfonyl fluoride derivative, the method comprises (a) reacting a benzenesulfonyl fluoride derivative represented by structural formula 1 with an organolithium represented by structural formula 2, thus synthesizing an intermediate represented by structural formula 3 in reaction scheme 1 and (b) reacting the intermediate with an electrophile, thus synthesizing a compound represented by structural formula 4 or a compound represented by structural formula 4′. The present disclosure enables the synthesis of several functionalized sulfonyl fluorides within a few seconds under mild temperature conditions in addition to the chemistry of Sulfonyl Fluoride Exchange (SuFEx), which is a next-generation click chemistry, so that sulfonyl fluoride, the main reactant of the SuFEx reaction, can be efficiently secured.

摘要:The invention provides methods for the synthesis of eribulin or a pharmaceutically acceptable salt thereof (e.g., eribulin mesylate) through a macrocyclization strategy. The macrocyclization strategy of the present invention involves subjecting a non-macrocyclic intermediate to a carbon-carbon bond-forming reaction (e.g., an olefination reaction (e.g., Homer-Wadsworth-Emmons olefination), Dieckmann reaction, catalytic Ring-Closing Olefin Metathesis, or Nozaki-Hiyama-Kishi reaction) to afford a macrocyclic intermediate. The invention also provides compounds useful as intermediates in the synthesis of eribulin or a pharmaceutically acceptable salt thereof and methods for preparing the same.
