mercaptoacetic acid afforded new (β -lactam (3a–c) and New thiazolidinone (4a–c) derivatives, respectively. In addition, 1 reacted with chloroacetyl chloride in presence of ethanol and triethylamine to give 6. compound 6 react with different nitroso compounds to give Schiff bases (7a–c) which underwent cyclization with chloroacetyl chloride and/or mercaptoacetic acid to give spiro (β -lactam (8a–c) and spiro thiazolidinone
