fluorene derivatives has been developed by devising a rhodium-catalyzed stitching reaction/remote nucleophilic substitution sequence. A variety of nucleophiles can be installed in the second step including both heteroatom and carbon nucleophiles. An efficient synthesis of 5H-benzo[a]fluoren-5-ones has also been realized using N-(2-alkynyl)benzoylpyrrole as the reaction partner through a new reaction pathway
通过设计铑催化的拼接反应/远程亲核取代序列,已经开发了多取代芴衍生物的三组分合成方法。第二步中可以安装各种亲核试剂,包括杂原子亲核试剂和碳亲核试剂。N-(2-炔基)苯甲酰基吡咯通过新的反应路径作为反应伙伴,也已经实现了5 H-苯并[ a ]芴-5-酮的高效合成。
