Kamijo, Shin,Sasaki, Yuya,Yamamoto, Yoshinori
, p. 35 - 38 (2004)
A copper-catalyzed tandem reaction between 2-alkynyl-N-arylideneanilines and alcohols is found to produce N-(alkoxybenzyl)indoles in good to high yields. A wide variety of substituted N-(alkoxybenzyl)indole derivatives can be synthesized by utilizing this
Selectivity for Alkynyl or Allenyl Imidamides and Imidates in Copper-Catalyzed Reactions of Terminal 1,3-Diynes and Azides

supporting information, p. 697 - 701 (2021/02/01)
Copper-catalyzed reactions of terminal 1,3-diynes with electron-deficient azides to generate either 3-alkynyl or 2,3-dienyl imidamides and imidates are described. The selectivity depends on the diyne substituents and the nucleophile that reacts with the ketenimide intermediate generated from the corresponding triazole precursor. Reactions of 1,3-diynes containing a propargylic acetate afford [3]cumulenyl imidamides, while reactions using methanol as the trapping agent selectively generate 2,3-dienyl imidates. Five-membered heterocycles were obtained from 1,3-diynes containing a homopropargylic hydroxyl or amine substituent.
