Abstract
In this work we have investigated stereoselective synthesis of cis and/or trans beta-lactams under diverse conditions. Ten different reaction conditions have been used for this study. It is important to note that the stereochemistry of the beta-lactam formation reaction depends on the conditions of the experiments, structures of the imines and acid chlorides, order of addition of the reagents, reaction temperature and solvents. To summarize the results, mathematical graphs are plotted.
