We demonstrated a ruthenium-catalyzed regioselective allylic amination of tertiary allylic esters with various amines using [Cp*Ru(CH3CN)3][PF6]/5,5′-dimethyl-2,2′-bipyridine (5,5′-diMe-2,2′-bpy) a...
rings: Treatment of N‐arylallylamine with an aryl or alkenylhalide under palladium catalysis (see scheme; dba=dibenzylideneacetone, SPhos=2‐dicyclohexylphosphanyl‐2′,6′‐dimethoxybiphenyl) resulted in intramolecular cyclization to form the arylmethyl‐substituted aziridine with concomitant CC bond formation. The experiments for the elucidation of the reaction mechanism are also described.
