- Аннотация: Easily accessible [(5,6-dihydro-4H-1,2-oxazin-3-yl)methyl]malonates 1 were converted into substituted 5-(3-hydroxypropyl)pyrrolidin-2-ones 2 and pyrrolizidinones 3, which are versatile products and intermediates for organic and bioorganic chemistry. The synthetic sequence suggested includes stereoselective two-step reduction of an oximino fragment, followed by intramolecular cyclization involving one of the CO2Me groups and decarboxylation in the last stage. The efficiency of this strategy was demonstrated by the stereoselective synthesis of pyrrolizidinone rac-4, a highly efficient analogue of antidepressant Rolipram, from nitroethane.
