The concave position of the proton in protonated concave pyridines 8*H+ or 9*H+ leads to increased selectivities in protonation reactions of nitronate anions 2a-d.Thus, the reprotonation of the nitronate anion 2a by the protonated concave pyridine 8*H+ selectively yields the nitro compound 1a whereas the nitronate anions 2b-d are transformed to the Nef products 4b-d.
