摘要：

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 Net products 4b–d.
