  几种α-溴缩醛的碱催化脱溴化氢

  摘要：

  从 α-溴乙醛和乙二醇的同系物[2-(α-溴烷基)-1,3-二氧杂环己烷]或1,3-丙二醇得到的缩醛在叔丁醇中用叔丁醇钾碱催化脱卤化氢[2-(α-溴烷基)-1,3-二恶烷]提供相应的乙烯酮缩醛，在某些情况下仅作为主要产物，在其他情况下作为主要产物以及较小比例的α,β-不饱和缩醛。相比之下，类似的脱卤化氢条件将从 α-溴乙醛和单羟基醇的同系物获得的缩醛转化为 α,β-不饱和缩醛，在某些情况下仅转化为 α,β-不饱和缩醛，而在其他情况下则作为主要产物伴随着较小比例的相应乙烯酮乙缩醛。优先选择由 2-(α-溴代烷基)-1 形成烯酮缩醛，3-二氧戊环（亚乙基缩醛）被认为是由于 1,3-二氧戊环的形状受限，碱更容易接近次甲基质子。通过碱基对α-溴的次甲基质子的逼近...

  (Poly)glycerol monoethers were synthesized in good yield and selectivity by the catalytic reductive alkylation of glycerol, diglycerol, and triglycerol with readily available, cheap and/or bio‐sourced carboxylic acids. The reaction was catalyzed by 1 mol % of Pd/C under 50 bar H2 using an acid ion‐exchange resin as a recyclable cocatalyst. The catalytic system was recycled several times, and a mechanism
