    Controllable Skeletal and Peripheral Editing of Pyrroles with Vinylcarbenes
    摘要:
    The skeletal editing of azaarenes through insertion, deletion, or swapping of single atoms has recently gained considerable momentum in chemical synthesis. Here, we describe a practical skeletal editing strategy using vinylcarbenes in‐situ generated from trifluoromethyl vinyl N‐triftosylhydrazones, leading to the first dearomative skeletal editing of pyrroles through carbon‐atom insertion. Furthermore, depending on the used catalyst and substrate, three types of peripheral editing reactions of pyrroles are also disclosed: α‐ or γ‐selective C–H insertion, and [3+2] cycloaddition. These controllable molecular editing reactions provide a powerful platform for accessing medicinally relevant CF3‐containing N‐heterocyclic frameworks, such as 2,5‐dihydropyridines, piperidines, azabicyclo[3.3.0]octadienes, and allylated pyrroles from readily available pyrroles. Mechanistic insights from experiments and density functional theory (DFT) calculations shed light on the origin of substrate‐ or catalyst‐controlled chemo‐ and regioselectivity as well as the reaction mechanism.

  • Tandem sequential catalytic enantioselective synthesis of highly-functionalised tetrahydroindolizine derivatives

    An isothiourea-catalysed enantioselective synthesis of novel tetrahydroindolizine derivatives is reported through a one-pot tandem sequential process. The application of 2-(pyrrol-1-yl)acetic acid in combination with either a trifluoromethyl enone or an α-keto-β,γ-unsaturated ester in an enantioselective Michael addition–lactonisation process, followed by in situ ring-opening and cyclisation, led to

    trifluoromethyl ketones is described. The notable features of this tandem process are its operational simplicity, easily accessible starting materials, and mild reaction conditions. The corresponding trifluoromethylated pyranopyrazoles were obtained in excellent yields (85–99%) with good to excellent diastereoselectivities (6:1–30:1). In addition, the stereochemical assignment of the major isomer by X-ray crystallographic

    Enantioselective formal hetero‐DielsAlder reactions of trifluoromethylated enones and 2‐amino‐1,3‐butadienes generated in situ from aliphatic acyclic enones and chiral primary amines are reported. The corresponding tetrahydropyran‐4‐ones are formed in up to 94 % yield and with up to 94 % ee. The reaction was carried out through a stepwise mechanism, including initial aminocatalytic aldol condensation

  • Isothiourea-mediated asymmetric Michael-lactonisation of trifluoromethylenones: a synthetic and mechanistic study

    HBTM-2.1 promotes the catalytic asymmetric intermolecular Michael-lactonisation of arylacetic acids and trifluoromethylenones in the presence of pivaloyl chloride, giving C(6)-trifluoromethyldihydropyranones with high diastereo- and enantiocontrol (up to 95 : 5 dr and >99% ee) that are readily derivatised to diverse synthetic building blocks containing trifluoromethyl-stereogenicity. Kinetic studies indicate the reaction is first order with respect to both in situ formed mixed anhydride and catalyst concentration, with a primary kinetic isotope effect observed using α,α-di-deuterio 4-fluorophenylacetic acid, consistent with rate determining deprotonation of an intermediate acyl isothiouronium ion.
    HBTM-2.1在有庚酰氯存在的情况下,促进了芳基乙酸和三甲烯酮的催化不对称分子间迈克尔-内酯化反应,生成高二者立体选择性和对映选择性的C(6)-三甲基二氢吡喃酮(达到95 : 5的dr和>99% ee),这些产物可以方便地转化为含有三甲基手性基团的多样合成构件。动力学研究表明,反应对原位生成的混合酸酐和催化剂浓度均为一级反应,同时在使用α,α-二4-氟苯乙酸的实验中观察到了主要的动力学同位素效应,这与中间体酰基异尿阳离子的去质子化作为速率限制步骤一致。
