A transition metal salt catalyzed alkyne carbonyl metathesis followed by a multicomponent protocol to synthesize highly substituted new (1′S,2′R,3′R,7a′R)‐1′,3′,5′,6′,7′,7a′‐hexahydrospiro[indoline‐3,2′‐pyrrolizin]‐2‐ones. A total of 39 compounds were synthesized by an interesting combination of metal‐salt catalysis and a multicomponent strategy.
过渡金属盐催化炔羰复分解,接着多组分协议合成高度取代的新的(1'小号,2' - [R,3' - [R,7A' - [R)-1',3',5',6',7' ,7a'-六氢螺[吲哚啉-3,2'-吡咯烷] -2-。通过金属盐催化和多组分策略的有趣结合,总共合成了39种化合物。
