Studies on lactams. Part XIII. A position isomer of a penam (4-thia-1-aza-bicyclo[3,2,0]heptane)
Abstract
Cycloaddition of azidoacetyl chloride and a 3-thiazoline has been used to synthesize the 6-azido-, 6-amino-, and 6-phthalimido- derivatives of a penam in which the position of the sulphur atom in the thiazolidine ring has been altered.
