Rh(III)‐Catalyzed C−H Activation/Annulation of N‐Methyl Arylhydrazines with Iodonium Ylides toward Ring‐fused Cinnolines
Asian Journal of Organic Chemistry(2022)
摘要
The first Rh(III)‐catalyzed annulation of N‐methyl arylhydrazines with iodonium ylides was developed. This transformation undergoes cascade C−H activation/annulation, dehydration and demethylative aromatization under very simple reaction conditions, providing a series of oxycycloalkyl‐fused cinnolines in good yields.
