Description

Potassium (S)-oxirane-2-carboxylate is a chiral epoxide reagent featuring a stereodefined oxirane ring and carboxylate counterion. This bench-stable, moisture-tolerant compound enables enantioselective transformations in asymmetric synthesis, integrating readily into catalytic systems for C–C bond formation.

Application

Potassium (S)-oxirane-2-carboxylate serves as a chiral building block for asymmetric synthesis, enabling stereoselective ring-opening reactions with nucleophiles to install functionalized β-hydroxy carboxylates. Its bench-stable solid form and predictable stereochemical integrity facilitate reliable use in medicinal chemistry and natural product synthesis workflows.
