Respiratory protection
Where risk assessment shows air-purifying respirators are appropriate use a full-face respirator with
multi-purpose combination (US) or type ABEK (EN 14387) respirator cartridges as a backup to
engineering controls. If the respirator is the sole means of protection, use a full-face supplied air
respirator. Use respirators and components tested and approved under appropriate government
standards such as NIOSH (US) or CEN (EU).
Hand protection
Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique (without
touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves
after use in accordance with applicable laws and good laboratory practices. Wash and dry hands.
The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the
standard EN 374 derived from it.
Eye protection
Safety glasses with side-shields conforming to EN166 Use equipment for eye protection tested and
approved under appropriate government standards such as NIOSH (US) or EN 166(EU).
Skin and body protection
impervious clothing, The type of protective equipment must be selected according to the concentration
and amount of the dangerous substance at the specific workplace.
Hygiene measures
Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at
the end of workday.

  Tris(fluoroalkoxy)methylphosphonium salts in the synthesis of methylphosphoranes

  摘要：

  The reactions of phosphites containing electron-withdrawing fluoroalkyl groups with methyl triflate gave tris(fluoroalkoxy)methylphosphonium triflates, which react with alcohols to give either tetrakis(fluoroalkoxy)methylphosphoranes (in the case of fluoroalcohols) or alkylation products - ethers and bis(fluoroalkoxy)methylphosphonates (in the case of unsubstituted alcohols). The structures of the phosphonium salts and phosphoranes were supported by H-1 and P-31 NMR spectroscopy.

• DBU-promoted alkylation of alkyl phosphinates and H-phosphonates

  日期：2012.9

  phosphinates and some H-phosphonate diesters is promoted by the base DBU. Only more reactive alkyl halides react in preparatively useful yields. However, the method provides easy access to important H-phosphinate building blocks, without the need for a protecting group strategy or metal catalysts. The reaction is conveniently conducted at, or below, room temperature. The preparation of methyl-H-phosphinate

  DBU碱促进烷基次膦酸酯和一些H-膦酸酯二酯的烷基化。只有更多的反应性烷基卤化物以制备有用的产率反应。但是，该方法无需重要的保护基策略或金属催化剂即可轻松获得重要的H-次膦酸酯结构单元。该反应方便地在室温或低于室温下进行。甲基的制备ħ -phosphinate酯是特别令人感兴趣的，因为它避免了以往更普遍使用methyldichlorophosphine MePCl的2。

Not only does the compound possess fascinating biological activity, but it also presents an opportunity to test current methods for chemical synthesis and provides an inspiration for new reaction development. A new synthesis of discodermolide employs a previously undisclosed stereoselective catalytic diene hydroboration and also establishes

  Herein, we report a robust total synthesis of dictyostatin. This polyketide natural product has attracted much attention because of its impressive antiproliferative activity against several human cancer‐cell lines. We accomplished its synthesis in a highly convergent manner from three fragments of equal complexity, which were prepared on multigram scale. The southern and northwestern subunits were

  在这里，我们报告了dictyostatin的鲁棒的总合成。这种聚酮化合物天然产物因其对多种人类癌细胞系的令人印象深刻的抗增殖活性而备受关注。我们从高度相同的三个片段（以多克级尺度制备）以高度收敛的方式完成了其合成。南部和西北亚单元是通过应用我们的o‐DPPB指导的加氢甲酰化和烯丙基取代方法。这些方法产生了具有良好非对映选择性的dictyostatin的C6和C14立体中心，并同时分别允许通过Wittig烯化和Sharpless不对称环氧化进一步加工片段。在实用性，选择性和规模方面，加氢甲酰化和烯丙基取代的引人注目的性能突显了它们在丙酸酯基序构建中的价值。

• Anomalous Z-isomer content in Wittig reaction products from keto-stabilised ylides with ortho-heteroatom substituted benzaldehydes
  作者：Peter A. Byrne、Lee J. Higham、Pádraic McGovern、Declan G. Gilheany

  DOI：10.1016/j.tetlet.2012.09.123

  日期：2012.12

  Wittig reaction products of keto-stabilised ylides with ortho-substituted benzaldehydes are found to show significantly higher than expected Z-alkene content (up to 50%) compared to analogous reactions of the same ylides with benzaldehyde itself. A cooperative effect is seen whereby the unusual Z-content is further augmented if the ylide bears greater steric bulk in the α′-position. These results are

  与相同的酰基化物与苯甲醛本身的类似反应相比，发现酮稳定的酰基化物与邻位取代的苯甲醛的维蒂希反应产物显示出显着高于预期的Z-烯烃含量（高达50％）。观察到协同作用，如果叶立德在α'-位置具有较大的空间体积，则异常Z含量会进一步增加。这些结果与我们先前关于所有内鎓盐类型与带有β-杂原子的醛的反应的观察结果一致。值得注意的是，以前仅在半稳定化的基团上才能看到的协同作用现已扩展到稳定化的基团。Z都异常增加-含量和协同作用可以在Wittig反应的[2 + 2]环加成机理内合理化。
