How is trans-2-Phenylcyclopropanecarboxylic acid (CAS: 939-90-2) typically synthesized?

Trans-2-Phenylcyclopropanecarboxylic acid can be synthesized via a multi-step process involving the formation of a cyclopropane ring followed by alkylation and carboxylation. Commonly, this involves the use of lithium dialkylcuprates as nucleophiles and carboxylation with carbon dioxide. The reaction conditions include the use of a Lewis acid catalyst and appropriate solvents to ensure high selectivity and yield.
