Article abstract of DOI:10.1016/S0040-4039(99)00993-4

Ring closing metathesis of N,N-diallylanilines and a related 1,2- dihydroquinoline, catalysed by Grubbs' catalyst, occurs in good yield at room temperature furnishing 3-pyrrolines and 3-piperidines. DCM and EtOAc are the solvents of choice and interesting substituent effects are identified and discussed.
