Compounds 4 have been synthesized by cycloaddition reaction of, chloroacetyl chloride and
mercaptoacetic acid with the synthesized Shiff,s bases 5a-c to afford new spiroβ-Lactam 6a-c and
spirothiazolidinone7a-c the cycloaddition were characterized by spectral data including HNMR,13 CNMR, IR and elemental analysis.
