  Selenium promoted synthesis of enantiopure pyrrolidines starting from chiral aminoalcohols

  摘要：

  Starting from commercially available enantiomerically pure aminoalcohols and using simple conversions promoted by organoselenium reagents, several enantiomerically pure substituted pyrrolidines were prepared. After double protections (R)- or (S)-2-phenylglycinols were converted into the beta-amino selenides by displacing the tosyl group with phenyl selenolate anions. The phenylseleno group was then substituted by an allyl group by treatment with allyltributyltin and AIBN. The reaction of these allylic derivatives with electrophilic phenylselenium reagents afforded selenium containing pyrrolidines as the result of a 5-exo-trig cyclization. The pyrrolidine derivatives thus obtained were reductively deselenylated with triphenyltin hydride and AIBN. Moreover, the selenides were converted into the selenones, which easily gave substitution with different nucleophiles. Enantiopure 2,5-pyrrolidines containing azido, methylthio, cyano and iodo groups were thus obtained. (c) 2007 Elsevier Ltd. All rights reserved.

  Selenium-promoted synthesis of enantiopure octahydroindolizines, hexahydro-1H-pyrrolizines and hexahydro-3H-pyrrolizin-3-ones

  摘要：

  Enantiomerically pure disubstituted pyrrolidines, recently synthesized from commercially available enantiomerically pure beta-aminoalcohol, were used as starting materials to synthesize enantiomerically pure hexahydro-1H-pyrrolizines and octahydroindolizine through a cyclization reaction promoted by N-(phenylseleno)phthalimide. Similarly, starting from enantiopure 5-(hydroxymethyl)pyrrolidin-2-ones, enantiopure hexahydro-3H-pyrrolizin-3-ones were obtained. (C) 2008 Elsevier Ltd. All rights reserved.
