Synthesis of functionalized 1,3-indandiones containing-cyclopentenones and -benzotropones has been achieved by the reaction of 1,5-diphenylpenta-1,4-diyn-3-ones with 1,3-indandiones, bindone respectively. The developed method involves Michael-anti-Michael addition cascade reactions under transition-metal-free conditions. This is the first report to synthesise diverse benzotropone fused with 1,3-indandiones under transition metal-free conditions from bindone.
通过1,5-二苯基戊-1,4-二炔-3-酮分别与1,3-茚二酮、苯偶姻酮反应,实现了含环戊烯酮和苯并环庚三烯酮的功能化1,3-茚二酮的合成。所开发的方法涉及无过渡金属条件下的迈克尔-反迈克尔加成串联反应。这是首次在无过渡金属条件下从苯偶姻酮合成与1,3-茚二酮稠合的多种苯并环庚三烯酮的报道。
