  日期：1998.11

  The benzenesulfonylation, acetylation, methylation and benzylation at the 1 position of indole and its derivatives with bases such as NaOH, KOH and NEt3 are presented. By using weaker bases than the traditional ones (BuLi, NaNH2, etc.), the process is simpler, more general and leads to the products in 80–100% yields. The chemoselectivity in compounds bearing more than one nitrogen is also demonstrated

  日期：——

  Acetylation of 3-acetylindole (9) with acetyl chloride-aluminum chloride in nitrobenzene or methylene chloride gave 3, 5-diacetylindole (10) as the major product, together with 3, 6- and 3, 7-diacetylindole (11, 12) as minor products. The similar acetylation of ethyl 3-indolecarboxylate (16) also gave the 5-acetyl derivative (17a) as the major product, together with the 6-and 7-acetyl derivatives (18a, 19) as minor products. Oxidation of 1, 3-diacetylindole (15) with lead tetratrifluoroacetate gave 3-indolinones (22, 23) and a dimeric product (24).

  日期：2018.3

  halogen-free Friedel–Crafts acylation protocol with virtually no waste stream generation. We propose a hydrogen bonding donor solvent will form a hydrogen bonding network and may provide significant rate enhancement for Friedel–Crafts reactions. Trifluoroacetic acid is one of the strongest H-bond donor solvents, which is also volatile and can be easily recovered by distillation without need for reaction workup

  我们已经开发了一种无金属，无卤素的Friedel-Crafts酰化方案，几乎没有废物流产生。我们建议氢键供体溶剂将形成氢键网络，并可能显着提高Friedel-Crafts反应的速率。三氟乙酸是最强的氢键供体溶剂之一，它也是易挥发的，可以通过蒸馏容易地回收而无需进行反应后处理。我们的方案是“绿色”的Friedel-Crafts酰化工艺：1）催化剂可以回收再利用；2）使用无卤素的起始原料（羧酸酐或羧酸）；3）无需进行水相反应后处理；4）最少或没有废蒸汽产生。

  The intramolecular Diels−Alder reaction between an amidofuran moiety tethered onto an indole component was examined as a strategy for the synthesis of Aspidosperma alkaloids. Furanyl carbamate 23 was acylated using the mixed anhydride 26 to provide amidofuran 22 in 68% yield. Further N-acylation of this indole furnished 27 in 88% yield. Cyclization precursors were prepared by removing the carbamate

  拴在吲哚成分上的酰胺基呋喃部分之间的分子内Diels-Alder反应已被检测为合成Asperdosperma生物碱的策略。使用混合酸酐26将氨基甲酸呋喃酯23酰化，以68％的产率提供酰胺基呋喃22。该吲哚的进一步N-酰化得到27，收率88％。环化前体通过除去氨基甲酸酯部分，随后加入N-制备-用适当的卤代烷进行烷基化。酰胺基氮原子上的较大取代基会导致酰胺基呋喃的反应性s-反式构型更高，从而促进Diels-Alder环加成反应。该反应需要在吲哚氮上存在吸电子取代基，以便进行环加成反应。的治疗N-烯丙基bromoenamide 48与Ñ -Bu 3 SNH / AIBN优先引导到6-内TRIG环化产物50，具有较高的稀释条件下而获得的最好的产率（91％）。最初衍生自48的环己烯基产生五环杂环50 通过直接的6-endo trig环化，或通过乙烯基自由基重排途径。
