Interest in β-amino esters and β-lactams has grown significantly due to their applications in the synthesis of compounds of pharmaceutical interest. Examples include β-lactam antibiotics such as the penicillin and carbapenem families. Because β-lactams and β-amino esters share a common pathway, methods to prepare either are often contaminated and thus complicated by the formation of the other. We have developed convenient and highly controllable method which can afford either product cleanly.

Flash photolysis has proven to be an effective technique for determining reaction mechanisms. Upon photolysis, a CO ligand is removed from Cr(CO)6 forming the reactive molecular fragment Cr(C0)5. In the presence of alkene, L, Cr(CO)s can react to form the meta-stable intermediate Cr(C0)5L. At high L concentrations, Cr(CO)5L decays by pseudo-first-order kinetics with an observed rate constant, kobs, which is dependent on the concentration of both L and added CO. The exar.t nature of the dependence provides insight into the mechanism of the decay of Cr(C0)5L and a plot of 1/kobs vs. [L] will give the rate constants for both …
