  • Modular Synthetic Approach to Silicon-Rhodamine Homologues and Analogues via Bis-aryllanthanum Reagents
    作者:Alexey N. Butkevich
    DOI:10.1021/acs.orglett.1c00512
    日期:2021.4.2
    A modular synthetic approach toward diverse analogues of the far-red fluorophore silicon-rhodamine (SiR), based on a regioselective double nucleophilic addition of aryllanthanum reagents to esters, anhydrides, and lactones, is proposed. The reaction has improved functional group tolerance and represents a unified strategy toward cell-permeant, spontaneously blinking, and photoactivatable SiR fluorescent
    提出了一种基于芳基镧试剂与酯、酸酐和内酯的区域选择性双亲核加成的远红荧光团硅罗丹明(SiR)的多种类似物的模块化合成方法。该反应提高了官能团耐受性,代表了一种针对细胞渗透、自发闪烁和光激活 SiR 荧光标记的统一策略。它与钯催化的羟基或氨基羰基化相结合,为一系列经过验证的活细胞兼容荧光染料提供了一条简化的合成途径。

    coumarin derivatives via a tandem double bond isomerization/oxidative cyclization of cinnamic acids. Inexpensive and stable xanthone was used as the photocatalyst, and readily available Selectfluor was used as the oxidant. This method tolerates a wide range of functional groups and offers excellent chemical yields in general. Besides, the photocatalytic oxidative cyclization of cinnamic acid esters gives
    我们已经通过肉桂酸的串联双键异构化/氧化环化开发了一种香豆素衍生物的有效光催化合成方法。廉价,稳定的x吨酮用作光催化剂,易购的Selectfluor用作氧化剂。该方法可耐受各种官能团,并且通常可提供出色的化学收率。此外,肉桂酸酯的光催化氧化环化得到二聚的木脂素型产物。
  • Generation of Alkyl Radical through Direct Excitation of Boracene-Based Alkylborate
    作者:Yukiya Sato、Kei Nakamura、Yuto Sumida、Daisuke Hashizume、Takamitsu Hosoya、Hirohisa Ohmiya
    DOI:10.1021/jacs.0c04456
    日期:2020.6.3
    The generation of tertiary, secondary, and primary alkyl radicals has been achieved by the direct visible-light excita-tion of a boracene-based alkylborate. This system is based on the photophysical properties of the organoboron mole-cule. The protocol is applicable to decyanoalkylation, Giese addition, and nickel-catalyzed carbon-carbon bond for-mations such as alkyl-aryl cross-coupling or vicinal

Their excited-state redox potentials, PC*/PC.- (up to 1.65 V) and PC.+ /PC* (up to -1.77 V vs. SCE), are such that these novel PCs can engage in both oxidative and reductive quenching mechanisms with strong thermodynamic requirements. The potential of these bimodal PCs was benchmarked in synthetically relevant photocatalytic processes

    Methods are reported for the efficient assembly of a series of phenol-derived propiolates, including the parent system 56, and their Au(I)-catalyzed cyclization (intramolecular hydroarylation) to give the corresponding coumarins (e.g., 1). Simple syntheses of natural products such as ayapin (144) and scoparone (145) have been realized by such means, and the first of these subject to single-crystal
