Herein a rhodium (III)‐mediated catalysis was demonstrated for approaching the structurally divergent N,N‐bicyclic pyridazine analogues. The pyrazolidinone moiety was used to direct the ortho C−H activation and this led to a general synthesis of benzopyridazine analogues with satisfactory yields. The crucial effect of the base was illustrated in the sequential dehydration process. For mechanistic insight
在本文中,铑(III)介导的催化被证明可以接近结构上不同的N,N-双环哒嗪类似物。吡唑烷酮部分用于指导邻域C H活化,这导致了苯并哒嗪类似物的普遍合成,并获得了令人满意的收率。在连续脱水过程中说明了碱的关键作用。为了获得机械学见解,进行了控制实验以说明催化环。进行了革兰氏合成和一些实际的转化,以供进一步应用。
