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.
