Abstract
The title compound, C26H23F2NO3S, a polysubstituted piperidine enol, adopts a twisted half-chair conformation. The crystal structure is stabilized by N-H center dot center dot center dot F, C-H center dot center dot center dot O and weak C-H center dot center dot center dot pi interactions. An intramolecular O-H center dot center dot center dot S interaction generates an S( 5) graph-set motif.
