c1cnn2ccnc2c1

A Bemis-Murcko scaffold is what remains of a molecule when every side chain is removed: the rings and the chains that link them. Chemicals that share a scaffold often belong to the same compound series, which helps when you look for analogues, alternative suppliers or related building blocks.
