摘要：
Enantiopure 3-(omega-hydroxyalkyl)-2-pyrrolidinones 7 and 9 were synthesised by Michael-addition of nitromethane to chiral alpha-alkylidenelactones 1 followed by reduction of the resulting 3-(beta-nitroalkyl)-lactones and ring transformation of the intermediate 3-(beta-aminoalkyl)-lactones. In an analogous manner the naturally occurring costuslactone 10 was transformed into the butyrolactam 12. (C) 1999 Elsevier Science Ltd. All rights reserved.
