A new synthetic method for the preparation of 4,5-unsubstituted 2,3-dihydroisoxazoles from readily available 5-acetoxyisoxazolidines is presented. Elimination reactions are carried out in anhydrous N-methylpyrrolidin-2-one (NMP) with a catalytic amou

Synthesis of trihydroxylated pyrrolizidines, the enantiomer of 2-epihyacinthacine A2 and indolizidine analogues of the natural alkaloids is reported. The key step of these syntheses is the stereoselective samarium diodide-induced coupling of the chir

Chiral nitrones 13-15 prepared from D-isoascorbic acid were found to effectively undergo an SmI2-mediated radical addition to methyl acrylate affording γ-N-hydroxylamino esters 19-22 with high diastereomeric control. The unsubstituted nitrone 14 aff
