Stereocontrolled syntheses of the diastereoisomeric 6-(1-hydroxyethyl)-2-ethylthio and 2-(2-aminoethylthio)-penem-3-carboxylates from a common monocyclic azetidinone precursor are described.Cu (I)-promoted cyclisation of suitable N/C-3 secopenems is shown to yield "isopenems" (7-oxo-2-thia-1-azabicyclo<3.2.0>hept-3-enes) as the sole bicyclic product.
