Abstract
Tributyltin hydride-mediated radical cyclization of 2,2-bis(phenylthio )ethenyl]-alpha-bromoalkanamides bearing (S)-1-phenylethyl group on th e nitrogen atom gave (4S)-4-bis(phenylthio)-methyl-2-azetidinones as m ajor products. The method was applied to the synthesis of a chiral pre cursor of carbapenem antibiotic (+)-PS-5.
