Abstract
The tricyclic ring system of the antiviral drug nevirapine has been employed to test the workability of the hydrated imidazoline ring expansion (HIRE) reaction which was previously exemplified for [1.4]oxazepine and [1.4]thiazepine counterparts. The imidazoline nucleus was grafted onto the lactam moiety of nevirapine in two high-yielding steps. Subsequent N-alkylation and the HIRE reaction proceeded as envisioned and delivered rare ring-expanded diarene-fused 1,4,7-triazecines with a diversity of alkyl substituents at the lactam nitrogen atom. These findings extend the scope of the HIRE reaction to the medicinally prominent [1.4]diazepine chemical space.
