  Organoselenium- and proton-mediated cyclization reactions of allylic amides and thioamides. Syntheses of 2-oxazolines and 2-thiazolines

  摘要：

  A variety of allylic amides and thioamides were treated with phenylselenenyl bromide in chloroform to give, via 5-exo cyclization, 2-oxazolines and 2-thiazolines, respectively, carrying a (phenylselenenyl)methyl substituent in the 5-position. In some cases (N-crotyl- and N-cinnamylamides/thioamides), dihydro-1,3-oxazines/-thiazines were formed via 6-endo cyclization. The phenylselenenyl group of the cyclofunctionalization products was slowly eliminated by treatment with m-chloroperbenzoic acid to introduce unsaturation in the resulting oxazoline/thiazoline. Reductive removal of the phenylselenenyl group was effected by treatment with triphenyltin hydride. This reaction was sometimes accompanied by a rearrangement of the heterocyclic ring. Proton-induced cyclizations of allylic thioamides to give 2-thiazolines was slowly but efficiently effected in boiling toluene containing a catalytic amount of p-toluenesulfonic acid.

  The discovery of distinct modes of asymmetric catalysis has the potential to rapidly advance chemists' ability to build enantioenriched molecules. As an example, the use of chiral cation salts as phase-transfer catalysts for anionic reagents has enabled a vast set of enantioselective transformations. A largely overlooked analogous mechanism wherein a chiral anionic catalyst brings a cationic species into solution is itself a powerful method. The concept is broadly applicable to a number of different reaction pathways, including to the enantioselective fluorocyclization of olefins, and dearomatization of aromatic systems with a cationic electrophile-transferring (e.g., fluorinating) agent and a chiral phosphate catalyst. The reactions proceed in high yield and stereoselectivity. The compounds and methods of the invention are of particular value, especially considering the scarcity of alternative approaches.

  发现不对称催化的不同模式具有潜力快速推动化学家构建手性富集分子的能力。例如，使用手性阳离子盐作为相转移催化剂用于阴离子试剂已经实现了大量手性选择性转化。一个被大多数人忽视的类似机制是手性阴离子催化剂将阳离子物种溶解到溶液中，这本身就是一种强大的方法。这一概念广泛适用于许多不同的反应途径，包括对烯烃进行手性选择性氟环化和用阳离子亲电试剂转移（例如，氟化）剂和手性磷酸盐催化剂进行芳香系统去芳构化。这些反应产率高，立体选择性好。该发明的化合物和方法具有特殊价值，尤其考虑到替代方法的稀缺性。

  Most of the precedent copper‐catalyzed trifluoromethylation reactions of unactivated alkenes concern terminal alkenes, and these processes are terminated in elimination, or nucleophilic addition, or semipinacol rearrangement, or CH bond functionalization steps. In this study, we develop a trifluoromethylation method for both unactivated terminal and internal alkenes to enable divergent late‐stage

  大多数未活化烯烃的先例铜催化的三氟甲基化反应的涉及末端烯烃，并且这些方法在消除或亲核加成，或重排semipinacol或C端的 H键的官能化步骤。在这项研究中，我们开发了一种针对未活化的末端烯烃和内部烯烃的三氟甲基化方法，以实现发散的后期自由基环化并实现高分子复杂性。这些环化与鲍德温规则完全一致。此外，进行了动力学同位素效应（KIE）的研究和控制反应，并提出了可能的机理。

  N-benzoyl-2-hydroxy-4-methylpyrrolidine, the key intermediate for the double carbonylation and the reductive annulation, is obtained selectivity in a Rh4(CO)12-catalyzed reaction of N-methallylamide. The hydrocarbonylations of this cyclic hemiamidal catalyzed by RhCl(PPh3)3, Co2Rh2(CO)12, and Co2(CO)8 give the corresponding double carbonylation product (2-formylpyrrolidine), reductive annulation product (pyrrolidine)

  N-烯丙基酰胺的酰胺导向的Rh催化的加氢甲酰化和Pd催化的加氢酯化分别得到具有良好区域选择性的异醛和酯。N-甲基烯丙基酰胺的Rh-和Co 2 Rh 2（CO）12催化反应分别通过新颖的双羰基化反应生成1-酰基-2-甲酰基吡咯烷，并通过还原环化分别生成1-酰基吡咯烷，选择性极好。在Rh 4（CO）12催化的N反应中，具有选择性的环状半缩醛N-苯甲酰基-2-羟基-4-甲基吡咯烷酮是双羰基化和还原性环化反应的关键中间体-甲基烯丙基酰胺。RhRh（PPh 3）3，Co 2 Rh 2（CO）12和Co 2（CO）8催化的环状环乙酰胺的羰基化反应产生相应的双羰基化产物（2-甲酰基吡咯烷），还原环化产物（吡咯烷），和酰胺羰基化产物（脯氨酸）的收率和选择性极好。在氘标记实验的基础上研究了新型双羰基化和还原性环化反应的机理，发现这些反应是通过烯酰胺中间体进行的，然后向烯酰胺中添加极富区域选择性的金属氢化物。

  We report the development of a new aminoxyl radical catalyst, CHAMPO, for the electrochemical diazidation of alkenes. Mediated by an anodically generated charge-transfer complex in the form of CHAMPO-N3, radical diazidation was achieved across a broad scope of alkenes without the need for a transition metal catalyst or a chemical oxidant. Mechanistic data support a dual catalytic role for the aminoxyl
