  Modular Preparation of 5-Halomethyl-2-oxazolines via PhI(OAc)₂-Promoted Intramolecular Halooxygenation of N-Allylcarboxamides

  摘要：

  A new method for the construction of oxazoline moiety was detailed. Using (diacetoxyiodo)benzene (PIDA) as the reaction promoter and halotrimethylsilane as the halogen source, intramolecular halooxygenation and halothionation of N-allylcarboxamides/N-allylcarbothioamides proceeded readily, leading : to the corresponding 5-halomethyloxazolines/5-halomethylthiazolines in good to excellent isolated yields. The 5-halomethyl products could be converted to different derivatives via conventional nucleophilic substitution methods. The reactions were carried out using easily available starting materials, and did not need harsh reaction conditions. All these features made this reaction a viable method for the construction of different oxazoline and thiazoline structures.

  摘要：

  环丙基酰胺的Rh催化的羰基C-C键活化生成结构稳定的Rhodacyclopentanones，其与（3 + 1 + 2）环加成中的链状烯烃结合。这些研究提供了多组分环加成反应的第一个例子，该过程通过“简单的”电子贫乏的环丙烷的C-C键活化而进行。

  The tandem cyclization of olefinic carbonyls with easily accessible diselenides facilitated by electrochemical oxidation has been successfully developed, which provides an environmentally friendly method for the construction of C–Se and C–O bonds simultaneously. A series of seleno dihydrofurans and seleno oxazolines, bearing fragile heterocycles, subtle C–I bonds and supernumerary vinyl groups, were

  已经成功地开发了通过电化学氧化促进具有容易获得的二硒化物的烯烃羰基的串联环化反应，这为同时构建C-Se和C-O键提供了一种环境友好的方法。使用这种优雅的螯合策略，可以伪造一系列带有易碎杂环，微妙的C–I键和大量乙烯基的硒代二氢呋喃和硒代恶唑啉。既不需要金属催化剂也不需要外部化学氧化剂来促进这种转变。

  using aromatic hydroxamic acid esters as the oxidizing directing group and allylic amides as unactivated olefin coupling partners, delivering a wide variety of aminomethyl isoquinolinones in good to excellent yields. This annulation is distinctive as allylic congeners typically result in allylation and not the annulation. Late-stage derivatization of a bioactive synthetic bile acid has been showcased
