| titleOfInvention | Process for the preparation of pyrrolidone derivatives |
| abstract | Process for preparing pyrrolidinone derivatives (1)in which R is hydrogen, alkyl or acyl characterised in that a compound of (2)wherein R' is hydrogen and R<sup>2</sup> is benzyl or substituted benzyl, or R' and R<sup>2</sup> can together form a groupwhere R<sup>4</sup> and R<sup>5</sup> are independently hydrogen, alkyl, phenyl or optionally substituted aryl or together are 1,4-butylene or 1,5-pentylene; R<sup>3</sup> is hydrogen or straight or branched alkyl of 1 to 4 carbon atoms; and X is alkyl subjected to N-deprotection and the deprotected intermediate is cyclized intramolecularly. The deprotected intermediates can be isolated as acid-addition salts. |
