Synthesis of Sulfonamide-Based Ynamides and Ynamines in Water

Ynamides, though relatively more stable than ynamines, are still moisture-sensitive and prone to hydration especially under acidic and heating conditions. Here we report an environmentally benign, robust protocol to synthesize sulfonamide-based ynamides and arylynamines via Sonogashira coupling reactions in water, using a readily available quaternary ammonium salt as the surfactant.

Gold-Catalyzed Intermolecular [4+2] Annulation of 2-Ethynylanilines with Ynamides: An Access to Substituted 2-Aminoquinolines

A gold-catalyzed intermolecular [4+2] annulation of easily accessible 2-ethynylanilines with ynamides offers a highly region-selective, modular, efficient, and atom-economical strategy for the synthesis of substituted 2-aminoquinolines in up to 93% yield. (Figure presented.).
