Methylation of 2,8-dimethyl-6H,12H-5,11-ethanodibenzo[b,f][1,5]-diazocine (ethano-Tröger's base) with methyl iodide followed by ion metathesis and fluorination with N-fluoro-2,3,4,5,6-pentachloropyridinium triflate affords a new electrophilic N-F reagent, that is more reactive than Selectfluor. 2D (19)F-(15)N HMQC experiments provide (1)JNF coupling constants which are diagnostic for the N-F functional group.

The typically planar amide when incorporated into bicyclic systems can undergo a significant distortion from planarity resulting in physical properties and reactivity that deviate from classical amide behaviour. Herein, we report a succinct protocol that utilises potassium permanganate to selectively α-oxygenate the benzylic position of ethano-Tröger's base derivatives to yield a new class of twisted bisamides. Additionally, we report the first synthesis of an ethano-Tröger's base derivative bearing substituents in the positions ortho to the nitrogen atoms.
