Chemical structures of GABA and<unk> , with commonalities highlighted<unk>  is a 3,3-disubstituted derivative of GABA. Therefore, it is a GABA analogue, as well as a γ-amino acid. Specifically, it is a derivative of GABA with a pentyl disubstitution at 3 position, hence, the name -<unk> , in such a way as to form a six-membered ring. After formation of the ring, the amine and carboxylic groups are not in the same relative positions as they are in the GABA:. they are more conformationally constrained. Synthesis Synthesis of<unk> . A chemical synthesis of<unk>  has been described starting from 1,1-diacetyl hexane annhydride.
