The endo trick: An endo ring closure onto the trigonal β carbon atom of α,β-unsaturated acceptors that are tethered to the indole nitrogen atom followed by amide cleavage enables the diastereoselective C-2 alkenylation of indoles with fully substituted double bonds. The carboxy group functions as a synthetically useful temporary tether (see scheme). Copyright
