  • MANGANESE (III) CATALYZED C--H AMINATIONS

    Reactions that directly install nitrogen into C—H bonds of complex molecules are significant because of their potential to change the chemical and biological properties of a given compound. Selective intramolecular C—H amination reactions that achieve high levels of reactivity, while maintaining excellent site-selectivity and functional-group tolerance is a challenging problem. Herein is reported a manganese perchlorophthalocyanine catalyst [Mn III (ClPc)] for intermolecular benzylic C—H amination of bioactive molecules and natural products that proceeds with unprecedented levels of reactivity and site-selectivity. In the presence of Brønsted or Lewis acid, the [Mn III (ClPc)]-catalyzed C—H amination demonstrates unique tolerance for tertiary amine, pyridine and benzimidazole functionalities. Mechanistic studies indicate that C—H amination proceeds through an electrophilic metallonitrene intermediate via a stepwise pathway where C—H cleavage is the rate-determining step of the reaction. Collectively these mechanistic features contrast previous base-metal catalyzed C—H aminations.
    直接将氮原子安装到复杂分子中的C-H键的反应具有重要意义,因为它们有可能改变给定化合物的化学和生物性质。实现高反应性,同时保持优秀的位点选择性和官能团耐受性的选择性分子内C-H胺化反应是一个具有挑战性的问题。本文报道了一种锰过氯酞菁催化剂[MnIII(ClPc)],用于分子间苄基C-H胺化反应,该反应在生物活性分子和天然产物中以前所未有的反应性和位点选择性进行。在Brønsted酸或Lewis酸的存在下,[MnIII(ClPc)]催化的C-H胺化展示了对叔胺、吡啶和苯并咪唑官能团的独特耐受性。机理研究表明,C-H胺化通过亲电金属亚硝烯中间体经过分步途径进行,其中C-H裂解是反应的速率决定步骤。总的来说,这些机理特征与之前基于贱金属催化的C-H胺化反应形成了对比。

    将氮直接安装到复杂分子的C - H键中的反应非常重要,因为它们具有改变给定化合物的化学和生物学特性的潜力。尽管选择性分子内C - H氨基化反应是已知的,但在保持出色的位点选择性和官能团耐受性的同时实现高水平的反应性仍然是分子间C - H氨基化的挑战。在这里,我们报道了一种用于生物活性分子和天然产物的分子间苄基C – H胺化反应的锰全氯酞菁催化剂[MnIII(ClPc)] ,其反应活性和位点选择性达到前所未有的水平。在布朗斯台德酸或路易斯酸的存在下,[MnIII(ClPc)]催化的C–氨基化显示出对叔胺,吡啶和苯并咪唑官能团的独特耐受性。机理研究表明,C - H氨基化反应可能通过逐步的途径通过亲电金属茂中间体进行,其中C - H裂解是反应的速率决定步骤。总的来说,这些机械特性与以前的贱金属催化的C - H胺形成对比,并为可调的选择性提供了新的机会。

    The invention provides novel manganese catalysts such as [Mn( t BuPc)], which are general for the amination of all types of C(sp 3 )-H bonds (aliphatic, allylic, propargylic, benzylic, ethereal), including strong 1 o aliphatic C—H bonds, while achieving excellent chemoselectivity, stereospecificity, and high functional group tolerance. We demonstrate the late-stage diversification of bioactive complex molecules that encompass the range of C(sp 3 )-H bond types, such as selective 1 o C—H aminations of betulinic acid and pleuromutilin derivatives. The catalysts' unprecedented balance of reactivity and selectivity is in part attributed to its mechanism of C—H amination that lies between stepwise and concerted.
    该发明提供了新型的锰催化剂,如[Mn(tBuPc)],适用于所有类型的C(sp3)-H键(脂肪族、烯丙基、丙炔基、苄基、乙醚基)的胺化,包括强1°脂肪族C—H键,同时实现优异的化学选择性、立体特异性和高官能团耐受性。我们展示了包括选择性1°C—H键胺化在内的生物活性复合分子的晚期多样化,这些复合分子涵盖了各种C(sp3)-H键类型,如对苯二酚酸和普鲁莫铁霉素衍生物的选择性1°C—H键胺化。催化剂在反应性和选择性之间的前所未有的平衡部分归因于其C—H键胺化机制介于逐步和协同之间。

    is an outlier to the reactivity–selectivity paradigm. It is unique in its capacity to functionalize all types of C(sp3)–H bond intramolecularly, while displaying excellent chemoselectivity in the presence of π functionality. Mechanistic studies indicate that [Mn(tBuPc)] transfers bound nitrenes to C(sp3)–H bonds via a pathway that lies between concerted C–H insertion, observed with reactive noble metals
    C–H键氧化反应强调了现有的范例,其中高反应性和高选择性成反比。能够氧化强脂族C(sp 3)–H键同时显示化学选择性(即对更多可氧化官能度的耐受性)的催化剂的开发仍未解决。在这里,我们描述了一种催化剂叔丁基酞菁锰[Mn(t BuPc)],它与反应性-选择性范式是一个离群值。它在分子内功能化所有类型的C(sp 3)-H键的能力方面具有独特性,同时在存在π官能团的情况下表现出出色的化学选择性。力学研究表明[Mn(tBuPc)]通过协调的C–H插入(通过反应性贵金属(如铑)观察到的C–H逐步逐步的C–H提取/反弹)之间的途径将结合的氮烯转移至C(sp 3)–H键。铁等贱金属。[Mn(t BuPc)]并没有实现效果的混合,甚至使1°的脂族和炔丙基C–H键氨基化,证明了以前已知的催化剂不寻常的反应性和选择性。
