catalytic amounts of gold and/or silver salts, the reaction of silyl enol ethers onto alkynes occurs under mild conditions to produce the corresponding polycyclic aromatic systems (acridine, quinoline or naphthalene cores) in good to high yields. Among the catalysts investigated, AgOTf has been chosen as a general catalyst for this reaction which likely proceeds through silver(I) activation of the alkynyl
描述了银/金催化的苯并环化反应。在催化量的金和/或银盐的存在下,甲硅烷基烯醇醚与炔烃的反应在温和条件下发生,以良好到高产率产生相应的多环芳族系统(吖啶、喹啉或萘核)。在所研究的催化剂中,已选择 AgOTf 作为该反应的通用催化剂,该反应可能通过银(I)活化炔基部分进行,导致随后的环异构化反应。
