The catalyst decides whether the syn or anti product is formed! In the cyclization of 1 , the ring‐closing metathesis of two double bonds that are located at a chiral and a prochiral center leads to the α,α′‐disubstituted pyrrolidine derivative 2 with viable diastereoselectivity. Tfa = trifluoroacetyl, [Ru] and [Mo] = Ru‐ and Mo‐carbene complexes, respectively.
