  手性磷酸催化烯基苯并咪唑的对映选择性氮杂Michael型加成反应

  摘要：

  N-保护的烯基苯并咪唑与吡唑或吲唑作为氮亲核试剂之间的高度对映选择性Michael型加成（MTA）反应是使用手性磷酸催化剂首次完成的。理论研究阐明了反应途径和立体化学结果的起源，其中苯并咪唑的催化剂取代基和N-保护基团导致了较高的对映选择性。

  Reaction of imidazoles with allyltributyltin in the presence of chloroformate

  摘要：

  The reaction of imidazoles with allyltributyltin in the presence of chloroformate gave 2-allyl-1,3-dialkoxycarbonyl-4-imidazolines in good yields. The addition products were aromatized with potassium ferricyanide under basic condition lo afford corresponding 2-allylimidazoles.

• Allylation of azoles with allyltributyltin via unstable N-(alkoxycarbonyl)azolium salts
  作者：Takashi Itoh、Hiroshi Hasegawa、Kazuhiro Nagata、Akio Ohsawa

  DOI：10.1021/jo00085a020

  日期：1994.3

  The one-pot reactions of imidazoles with allyltributyltin in the presence of alkyl chloroformates gave 2-allyl-1,3-bis(alkoxycarbonyl)-4-imidazolines in good yields. The reactions of thiazoles and oxazoles also proceeded in a similar manner. The instability of the intermediary quaternary salts required the nucleophiles to be added simultaneously with the chloroformate. Therefore, the reaction was specific for allyltributyltin, since it doesn't react with the carbonyl group of chloroformates. The dihydro allyl adducts thus obtained were aromatized with potassium ferricyanide under basic conditions to afford the corresponding 2-allylazoles.

  One pot synthesis of 2-substituted benzimidazoles/benzothiazoles through condensation is followed by cyclization of Weinreb amide with o-diaminoarene or o-aminothiophenol is reported. In the presence of boron trifluoride etherate in 1,4-dioxane solvent, a high yield (75-94%) was achieved within 60 min. Weinreb amide shows high selectivity in the reaction, even in presence of other active functional groups such as carboxyl, halogen, cyano, and methoxy. (c) 2013 Elsevier Ltd. All rights reserved.

  Herein we disclose results of our research into a novel class of benzimidazolium compounds active against malarial parasites. We have discovered that N-ferrocenylmethyl, N'-methyl-2-aryl (or styryl) benzimidazolium iodide salts show excellent in vitro activity against the P. falciparum malarial parasite strain NF54.
