We have found that the electron-rich Schiff bases can afford the cis-b-lactam ring even in the presence of the free hydroxyl functions. The mechanisms of cis and trans-b-lactam ring formation are discussed. The discussions are consistent with the recent publications.}, keywords = {Synthesis of Beta-Carbonhomologous,Synthesis of Cis-N-[Beta-carbobenzyloxy-Beta-(p-hydroxyphenyl)ethyl]-3-phathalimido-4-styryl-2-azetidinone,mechanisms of cis and trans-Beta-lactam ring formation}, url = {https://ijcce.ac.ir/article_12255.html}, eprint = {https://ijcce.ac.ir/article_12255_edcfd7861d93ee7dc51fc2988c12b33b.pdf} }
