Versuchsvorschrift

0.064 g of methyl 3-acetylthio-8-oxo-4,5-dithia-1-azabicyclo[4,2,0]oct-2-ene-2-carboxylate was dissolved in 1 ml of deuterochloroform and 0.063 g of triphenylphosphine added. TLC and NMR analysis indicated complete conversion of starting material to product. The crude product was chromatographed on silica gel using ethyl acetate/hexane as eluant to give 0.035 g (61%) of purified product.
