How is Sodium (2S,5R,6R)-3,3-dimethyl-7-oxo-6-{[(2R)-2-{[(2-oxo-1-imidazolidinyl)carbonyl]amino}-2-phenylacetyl]amino}-4-thia-1-azabicyclo[3.2.0]heptane-2-carboxylate (CAS: 37091-65-9) typically synthesized?

The synthesis involves multistep reactions including condensation, cyclization, and carboxylation. Commonly, imidazolidinyl carbonyl and phenylacetyl derivatives are used as starting materials. The overall yield is moderate, and the reaction is catalyzed by a transition metal such as palladium. High selectivity and purity are achieved through careful control of reaction conditions.
