C. Vaccher, Synthesis of 4-substituted-1,5-dihydro-2H-pyrrol-2-ones, potential synthons for the preparation of radiolabeled 3-substituted-gamma-amino acids, SYN COMMUN, 31(10), 2001, pp. 1481-1487
The preparation of 4-substituted-1,5-dihydro-2H-pyrrol-2-ones is described.
Those compounds can constitute precursors for radiolabeled 3-substituted-g
amma -amino acids, whose "cold" analogues show a good and specific affinity
for the GABA(B) receptor.
