Tröger's base analogues are of interest in areas such as host-guest chemistry, synthetic receptor design and asymmetric catalysis. We foresee that access to diverse functionality attached to the bridge of Tröger's base compounds will be beneficial for the development of these applications. As a starting point, we report a facile and general methodology to prepare a range of diversely functionalised 5,6,11,12-tetrahydrodibenzo[b,f][1,5]diazocines, compounds that may be viewed as "strap-clipped" Tröger's bases. As a demonstration of their reactivity, these compounds were reacted with benzaldehyde to introduce phenyl substituted straps onto a Tröger's base framework.
