    通过有机光氧化还原催化将 N-亚磺胺与烷基三氟硼酸盐统一:获得功能化的烷基亚磺酰胺和高价 S(VI) 类似物
    摘要:
    我们描述了一种有机光氧化还原催化的 sp 3 C-S 偶联,将N -亚磺胺与实验室稳定的烷基三氟硼酸盐作为潜在亲核对应物,高效地生成烷基亚磺酰胺。与传统有机金属试剂的双电子反应性相比,该催化方法报道了有机金属试剂与N-亚磺酰胺在C-S偶联中的单电子过程。这种温和且可扩展的方案提供了操作简单性和出色的官能团兼容性,包括酮、酯、酰胺、腈和卤化物,这些官能团容易受到有机锂或格氏试剂的影响。此外,亚磺酰胺可以方便地转化为各种重要的 S(VI) 化合物,如磺酰胺、磺酰亚胺和磺酰亚胺酯等。

    Copper-Catalyzed β-Boration of α,β-Unsaturated Carbonyl Compounds with Tetrahydroxydiborane
    摘要:
    The copper-catalyzed beta-boration of alpha,beta-unsaturated carbonyl compounds with tetrahydroxydiborane has been developed. This diboron reagent allows direct, efficient access to boronic acids and their derivatives. Primary, secondary, and tertiary alpha,beta-unsaturated amides are converted to the corresponding beta-trifluoroboratoamides in good to excellent yields. The beta-boration of a variety of alpha,beta-unsaturated esters and ketones is also reported.

    A rapid and highly selective oxidative cross-coupling reaction between readily available and shelf-stable arylboronic acids and primary or secondary potassium alkyltrifluoroborates was devised and developed, which works under mild conditions using copper(II) acetate as the catalyst and silver oxide as the oxidant. Initial experimental results indicate that a single-electron transmetalation process

    日期:2017.5.5
    An electrophilic, imide-based, visible-light-promoted photoredox/Ni-catalyzed cross-coupling reaction for the synthesis of aliphatic ketones has been developed. This protocol proceeds through N–C(O) bond activation, made possible through the lower activation energy for metal insertion into this bond due to delocalization of the lone pair of electrons on the nitrogen by electron-withdrawing groups.

    Designing molecular photocatalysts for potent photochemical reactivities ranks among the most challenging but rewarding endeavors in synthetic photochemistry. Herein, we document a quinoline-based organophotoredox catalyst, 2,4-bis(4-methoxyphenyl)quinoline (DPQN2,4-di-OMe), that could be assembled via the facile aldehyde–alkyne–amine (A3) couplings.

  • A General and Practical Route to Functionalized Bicyclo[1.1.1]Pentane‐Heteroaryls Enabled by Photocatalytic Multicomponent Heteroarylation of [1.1.1]Propellane

    Abstract

    1‐Aryl‐substituted bicyclo[1.1.1]pentanes (BCPs) are an important class of BCP derivatives with widespread application in drug development. Most syntheses of these materials require multiple chemical steps via BCP electrophiles or nucleophiles derived from [1.1.1]propellane. Although one‐step, multicomponent radical cross‐coupling reactions could provide a more sustainable and rapid route to access diverse heteroarylated BCPs, current approaches are limited to tertiary alkyl radicals, leading to a decrease in their practical value. In this study, a conceptually different approach enabled by a radical multicomponent heteroarylation of [1.1.1]propellane to access functionalized heteroarylated BCPs is described. Importantly, this protocol is compatible with primary‐, secondary‐, and tertiary aliphatic radicals, as well as various fluoroalkyl radical sources, thus enabling rapid library generation of sought‐after BCP derivatives for drug development.

    摘要1-芳基取代的双环[1.1.1]戊烷BCPs)是一类重要的 BCP生物,广泛应用于药物开发。这些材料的合成大多需要通过 BCP 亲电体或来自 [1.1.1]propellane 的亲核体进行多个化学步骤。虽然一步法多组分自由基交叉偶联反应可以为获得多种杂芳基化 BCP 提供更持久、更快速的途径,但目前的方法仅限于叔烷基自由基,导致其实用价值降低。本研究介绍了一种概念不同的方法,即通过 [1.1.1]propellane 的自由基多组分杂芳基化来获得官能化的杂芳基 BCP。重要的是,该方案与一级、二级和三级脂肪族自由基以及各种氟烷基自由基来源兼容,因此可以快速生成所需的 BCP生物库,用于药物开发。
