Saa. Ebrik et al., SYNTHESIS OF NOVEL PYRROLIDIN-2-ONES - GAMMA-AMINOBUTYRIC-ACID CYCLICANALOGS, Journal of heterocyclic chemistry, 35(3), 1998, pp. 579-583
Some new N-substituted pyrrolidin-2-ones, cyclic analogues of baclofen
and of 3-(5-methoxybenzo- [b]furan-2-yl)-gamma-aminobutyric acid, hav
e been prepared and characterized, starting from 4-(4-chlorophenyl) py
rrolidin-2-one and 4-(5-methoxybenzo [b] furan-2-yl)pyrrolidin-2-one.
