    通过将 TBADT 氢原子转移与镍催化合并进行醛的 C-H 烷基化
    摘要:
    催化剂控制的位点选择性 C-H 功能化是有机合成中具有挑战性但功能强大的工具。极性匹配和空间控制的氢原子转移 (HAT) 为位点选择性功能化提供了极好的机会。因此,双镍/光氧化还原系统成功地用于通过选择性甲酰基 C-H 活化从醛生成酰基自由基,随后交叉偶联生成酮,这是绝大多数天然和生物活性分子中普遍存在的结构基序。然而,仅开发了少数限制使用芳基卤化物的例子。鉴于胺的广泛可用性,我们首次使用经济的镍和 TBADT 催化剂通过 C-N 键断裂开发了交叉偶联反应。一系列烷基和芳基醛与苄基和烯丙基吡啶盐交叉偶联,以提供具有广谱官能团耐受性的酮。即使在α-亚甲基羰基或α-氨基/氧基亚甲基存在下,也获得了对甲酰基C-H键的高区域选择性。

  • Continuous-Flow Synthesis of Pyrylium Tetrafluoroborates: Application to Synthesis of Katritzky Salts and Photoinduced Cationic RAFT Polymerization
    作者:Carlo Sambiagio、Matteo Ferrari、Koen van Beurden、Nicola della Ca’、Jack van Schijndel、Timothy Noël

    日期:2021.3.19
    Katritzky salts have emerged as effective alkyl radical sources upon metal- or photocatalysis. These are typically prepared from the corresponding triarylpyrylium ions, in turn an important class of photocatalysts for small molecules synthesis and photopolymerization. Here, a flow method for the rapid synthesis of both pyrylium and Katrizky salts in a telescoped fashion is reported. Moreover, several
    Katritzky 盐已成为属或光催化下有效的烷基自由基源。这些通常由相应的三芳基吡咯鎓离子制备,而三芳基吡咯鎓离子又是用于小分子合成和光聚合的一类重要的光催化剂。在此,报道了一种以伸缩方式快速合成喃鎓盐和 Katrizky 盐的流动方法。此外,在流动和间歇条件下,在乙烯基醚的光诱导 RAFT 聚合中测试了几种喃鎓盐。
  • Nickel-Catalyzed Cross-Coupling of Alkyl Carboxylic Acid Derivatives with Pyridinium Salts via C–N Bond Cleavage

    The electrophile–electrophile cross-coupling of carboxylic acid derivatives and alkylpyridinium salts via C–N bond cleavage is developed. The method is distinguished by its simplicity and steers us through a variety of functionalized ketones in good to excellent yields. Besides acid chlorides, carboxylic acids were also employed as acylating agents, which enabled us to incorporate acid-sensitive functional

  • Photocatalytic deaminative benzylation and alkylation of tetrahydroisoquinolines with <i>N</i>-alkylpyrydinium salts
    作者:David Schönbauer、Carlo Sambiagio、Timothy Noël、Michael Schnürch
    DOI:10.3762/bjoc.16.74
    日期:——

    A ruthenium-catalyzed photoredox coupling of substituted N-aryltetrahydroisoquinolines (THIQs) and different bench-stable pyridinium salts was successfully developed to give fast access to 1-benzyl-THIQs. Furthermore, secondary alkyl and allyl groups were also successfully introduced via the same method. Additionally, the typically applied N-phenyl group in the THIQ substrate could be replaced by the cleavable p-methoxyphenyl (PMP) group and successful N-deprotection was demonstrated.

    一种以催化的光氧还偶联反应成功地将取代的N-芳基四氢异喹啉(THIQs)与不同的台阶稳定吡啶盐成功地结合,快速获得1-苄基-THIQs。此外,次烷基和烯丙基基团也成功地通过相同的方法引入。此外,THIQ底物中通常应用的N-苯基基团可以被可裂解的p-甲氧基苯基(PMP)基团取代,并且成功地展示了N-去保护。

    A stereoselective, denitrative cross-coupling of β-nitrostyrenes with N-alkylpyridinium salts for the preparation of functionalized styrenes has been developed. The visible-light-induced reaction proceeds without any catalyst at ambient temperature. Broad in scope and tolerant to multiple functional groups, the moderately yielding transformation is orthogonal to several traditional metal-catalyzed

    one of the most prevalent structural motifs in organic chemistry. Therefore, application of amines as alkylating agents in synthesis is highly compelling. Herein, we present a metal-free photoredox strategy for the formation of C(sp3)–C(sp) and C(sp3)–C(sp2) bonds from redox-activated primary amine derivatives. The developed reaction of 2,4,6-triphenylpyridinium salts with alkynyl p-tolylsulfones, leading
