General description

4-Hydroxy-2-pyrrolidinone is an important building block found in many bioactive compounds like streptopyrrolidine. It can be used as an intermediate in the synthesis of various γ-amino acids (GABA) and substituted 2-pyrrolidinones like cynometrine and cynodine.

Application

(S)-(−)-4-Hydroxy-2-pyrrolidinone can be used as a starting material in the preparation of:
  • Biologically significant pyrrolo[1,2:1′,2′]azepino[5,6-b]indole derivatives.
  • Substituted azepanes by reacting with various aldehydes via photochemical [5+2] cycloaddition.
