Enantiopure turbo chirality in small organic molecules, without other chiral elements, is a fascinating topic that has garnered significant interest within the chemical and materials science community. However, further research into application of this concept have been severely limited by lack effective asymmetric tools. To date, only few enantiomers targets isolated, these were obtained through physical separation using HPLC, typically on milligram scales. In work, we report first approach to enantiopure absence elements such as central axial chirality. This demonstrated assembling aromatic phosphine oxides, where three propeller-like groups are anchored P(O) center via axes. Asymmetric induction was successfully carried out sulfonimine auxiliary, with absolute configurations conformations unambiguously determined X-ray diffraction analysis. The resulting frameworks exhibit propellers arranged either clockwise (P,P,P) or counterclockwise (M,M,M) configuration. arrangements, bulkier sides rings oriented toward oxygen atom P=O bond rather than opposite direction. Additionally, orientational configuration controlled auxiliary well, showing one Naph pushed away from group (-CH2-NHSO2-tBu) phenyl ring. Computational studies conducted relative energies for rotational barriers target along axis transition pathway between two enantiomers, meeting our expectations. work expected impact fields chemistry, biomedicine, future.

Abstract Metal‐nitrenes are valuable reactive intermediates for synthesis and widely used to construct biologically relevant scaffolds, complexes functionalized molecules. The ring expansion of cyclic molecules via single‐nitrogen‐atom insertion nitrene or metal‐nitrenoid has emerged as a promising modern strategy driving advantageous nitrogen‐rich compound synthesis. In recent years, the catalytic single nitrogen atom into carbocycles, leading N‐heterocycles, become an important focus synthetic approaches with applications in medicinal chemistry, materials science, industry. Catalytic insertions have been increasing prominence organic due their capability high‐value added nitrogen‐containing heterocycles from simple feedstocks. this review, we will discuss rapidly growing field skeletal editing using transition metal catalysis access heterocycles, on across wide spectrum carbocycles.
