A mild, general, and efficient method for the synthesis of 2-monosubstituted and 2,5-disubstituted furans via the CuI-catalyzed cycloisomerization of alkynyl ketones was developed. It was demonstrated that furans containing both acid- and base-labile groups could be easily synthesized using this methodology. A plausible mechanism for this transformation is proposed.
开发了一种温和,通用,有效的方法,该方法通过CuI催化的炔基酮的环异构化反应合成2-单取代和2,5-二取代的呋喃。结果表明,使用该方法可轻松合成同时含有酸和碱不稳定基团的呋喃。提出了这种转换的合理机制。
