In the title compound, C22H27N2O2, the piperidine ring adopts a half-chair conformation with the benzene rings inclined in a trans orientation with respect to the piperidine ring [dihedral angle between the benzene rings = 89.1 (1)°]. In the crystal, a three-centre asymmetric N-H⋯O/C-H⋯O hydrogen-bonding inter-action leads to the formation of chains extending along the a-axis direction.

The asymmetric unit of the title compound, CHN·Br·CFI, contains one 2,2,6,6 tetra-methyl-piperidine-1-ium cation, one 1,2,3,4-tetra-fluoro-5,6-di-iodo-benzene mol-ecule, and one uncoordinated bromide anion. In the crystal, the bromide anions link the 2,2,6,6-tetra-methyl-piperidine mol-ecules by inter-molecular C-H⋯Br and N-H⋯Br hydrogen bonds, leading to dimers, with the coplanar 1,2,3,4-tetra-fluoro-5,6-di-iodo-benzene mol-ecules filling the space between them. There is a π-π interaction between the almost parallel benzene rings [dihedral angle = 10.

In the title mol-ecule, CHNO, the substituents on the phenyl ring are rotated slightly out of the mean plane of the ring but the piperidine moiety is nearly perpendicular to that plane. In the crystal, C-H⋯O hydrogen bonds form chains of mol-ecules extending along the -axis direction, which are linked by C=O⋯π(ring) inter-actions. A Hirshfeld surface analysis showed the majority of inter-molecular inter-actions to be H⋯H contacts while O⋯H/H⋯O contacts are the second most numerous.

Over the past decade, fentanyl-type new psychoactive substances (F-NPS) have emerged as the most representative synthetic opioids in third-generation drugs. These substances are characterized by their "low" fatal dose and parent drug levels in biological matrices, "fast" rates of derivatization and metabolism, and "many" derivatization sites and analogs. The low levels of parent fentanyl NPS in biological matrices complicate their detection, necessitating the use of characteristic metabolites as biomarkers for forensic analysis.

We recently reported a chiral phosphoric acid (CPA) catalyzed enantioselective photomediated ring contraction of piperidines and other saturated heterocycles. By extruding a single heteroatom from a ring, this transformation builds desirable C(sp)-C(sp) bonds in the ring contracted products; however, the origins of enantioselectivity remain poorly understood. In this work, enantioselectivity of the ring contraction has been explored across an expanded structurally diverse substrate scope, revealing a wide range of enantioselectivities (0-99%) using two distinct CPA catalysts.
