An Alternative Stereoselective Synthesis of ProtectedTrans-5-Alkyl-4-Hydroxy-2-Pyrrolidinones
摘要:
A flexible approach to protected trans-5-alkyl-4-hydroxy-2-pyrrolidinones was described. The key step involved the alpha-amidoalkylation of benzenesulfone derived from (S)-malic acid, with organozinc reagents generated in situ from Grignard reagents and anhydrous ZnCl2. OEt2.
