Thienodiazepine

A thienodiazepine is a heterocyclic compound containing a diazepine ring fused to a thiophene ring.

If R1 and R2 are part of a triazole ring it would be a thienotriazolodiazepine.

Thienodiazepine forms the central core of several pharmaceutical drugs including:

Bentazepam

Clotiazepam

Since thienodiazepines interact with the benzodiazepine receptor site, they typically have similar effects as benzodiazepines.
