Diazepine

Diazepine is a seven-membered heterocyclic compound with two nitrogen atoms (e.g., in ring positions 1 and 2).

Types include:

• 1,2-diazepine
• 1,3-diazepine
• 1,4-diazepine

When combined with a benzene ring, it is the basis of the benzodiazepine family of compounds. In these compounds the nitrogen atoms are at the 1 and 5 positions as, for example, in clobazam (depending on the position of the fused benzene ring, the nitrogen atoms are also given numbers 1 and 4).
