✦ Synopsis

The title compound were prepared aa useful optically active intermediates for the syntheals of "non-classical" B-lactam compounds. These monocyclic atetidinones were formed by cleavage of sulfur-carbon 5 bond of bicyclic penlcillanates with chlorine or tert-butyl hypochlorite in approplate solvents.
