Under Rh-catalyzed conditions, secondary amines and anilines function as directing groups to facilitate regioselective C–C bond activation of nonactivated cyclopropanes. The resulting amino-stabilized rhodacycles undergo carbonylative C–N bond formation en route to challenging seven- and eight-membered lactams. The processes represent rare examples where C–C bond oxidative addition of nonactivated cyclopropanes is exploited in reaction design.

非活化环丙烷的氮导向 C-C 键活化羰基化 N-杂环化

在 Rh 催化条件下，仲胺和苯胺作为导向基团促进非活化环丙烷的区域选择性 C-C 键活化。由此产生的氨基稳定的罗丹环在形成具有挑战性的七元和八元内酰胺的过程中经历了羰基化 C-N 键的形成。这些过程代表了在反应设计中利用非活化环丙烷的 C-C 键氧化加成的罕见例子。
