Rhodium(II)-catalyzed transannulation approach to N-fluoroalkylated indoles

Abstrakt

Copper(i)-catalyzed cycloaddition of substituted cyclohexenyl acetylenes with azido(per)fluoroalkanes afforded 4-cyclohexenyl-substituted N-(per)fluoroalkylated 1,2,3-triazoles. Their rhodium(ii)-catalyzed transannulation led to fused N-(per)fluoroalkyl pyrroles and subsequent oxidation provided N-(per)fluoroalkyl indoles.
