    Assembly of 4H-chromenes, imidazobenzothiazines and quinazolines via copper-catalyzed domino reactions using 2-halobenzyl tosylates as substrates
    摘要:
    The use of 2-halobenzyl tosylates as substrates in copper-catalyzed domino intermolecular substitution/intramolecular arylation processes for the efficient and selective preparation of heterocycles is reported for the first time. Reaction of 2-halobenzyl tosylates with beta-ketoesters delivers 4H-chromenes with yields ranging between 59 and 89%. Imidazobenzothiazines are formed with yields up to 82% upon reaction of 2-halobenzyl tosylates with 2-mercaptoimidazoles. When 2-halobenzyl tosylates are reacted with benzamidines the corresponding quinazolines are obtained. (C) 2014 Elsevier Ltd. All rights reserved.

    tandem palladium-catalyzed reaction involving a Suzuki–Miyaura coupling, a desulfenylative coupling, and a hydrothiolation of a triple bond is reported. Notably, the desulfenylative coupling occurs without copper(I) assistance and the hydrothiolation is totally regioselective and stereoselective. The overall process results in the double incorporation of the boronic acid and the reincorporation of
    据报道,一种新的串联钯催化的反应涉及Suzuki-Miyaura偶联,脱硫基偶联和三键的氢硫基化。值得注意的是,在没有铜(I)辅助的情况下发生了脱硫基偶联,并且氢硫基化是完全区域选择性和立体选择性的。整个过程导致硼酸的两次掺入和亚硫基部分的再掺入到产物结构中。从2-(溴苄基亚硫基)-1-炔丙基苯并咪唑开始,该转化导致带有立体定义的烯基硫的各种取代的苯并咪唑。
  • Synthesis of Benzimidazole-Fused Medium-Sized <i>N,S</i> -Heterocycles via Palladium-Catalyzed Cyclizations
    作者:Alexandra Basilio Lopes、Patrick Wagner、Mihaela Gulea
    DOI:10.1002/ejoc.201801686
    日期:2019.2.14
    Benzimidazole‐fused medium‐sized N,S‐heterocycles (8 to 10 ring atoms) having an exocyclic double bond were synthesized by using exo‐dig Pd‐catalyzed reductive cyclizations. In the case of two substrates bearing an N‐homopropargyl chain, a competing endo‐dig cyclocarbopalladation occurred, leading to rarely encountered 10‐ and 11‐membered N,S‐heterocycles with an endocyclic double bond.
