Olivanic Acid Analogues. Part 8. Halogenation and Sulphenylation Reactions leading Selectively to cis-Carbapenem Precursors; Stereospecific Synthesis of (+/-)-6-Epithienamycin

Introduction of halogen or sulphenyl substituents at C-7 of ketone 1, followed by stereospecific reduction steps, provides a selective route either to the (6RS,7RS,9RS) isomer 11 or to the (6RS,7RS,9SR) isomer 14 of 7-(1-hydroxyethyl)-8-oxo-3-oxa-1-azabic
