A series of polyfluorinated ortho-alkynylanilines – the versatile building blocks for diverse polyfluorobenzo azaheterocycles – have been synthesized by the Sonogashira reaction of polyfluorinated ortho-iodanilines with terminal alkynes.
Synthesis of functionalised 2,3-dihydroquinolin-4(1<i>H</i>)-ones <i>vs.</i> quinoline or <i>N</i>-alkenylindole derivatives through sequential reactions of 2-alkynylanilines with ketones
diversity-oriented synthesis of 2,2,3-substituted-2,3-dihydroquinolin-4(1H)-ones vs. functionalised quinoline or N-alkenylindole derivatives through Brønsted acid mediated or Lewisacid catalyzed sequential reactions of 2-alkynylanilines with ketones. In particular, a series of challenging quinolin-4-one derivatives are prepared with good functional group tolerance in an atom-economical fashion by using p-toluenesulfonic

CuI-catalyzed Intramolecular aminocyanation of terminalalkynes in N-(2-ethynylphenyl)-N-sulfonylcyanamides was initiated by the formation of Cu-acetylide to trigger N-CN bond cleavage of the N-sulfonylcyanamide moiety followed by CN migration to form...
