Abstract
Using the known peroxide oxidation of N‐benzyl‐3‐phenylseleno‐2‐pyrrolidinone with 30% hydrogen peroxide at −5°C after 3.5 h, we prepared the expected N‐benzyl‐3‐pyrrolin‐2‐one. However, reaction with 30% hydrogen peroxide for 12 h (−5°C→ambient) gave the unexpected product N‐benzyl‐5‐hydroxy‐3‐pyrrolidin‐2‐one in 84% isolated yield. This procedure is a new synthetic route to N‐benzyl‐5‐hydroxy‐3‐pyrrolidin‐2‐one.
