Abstract
An improved method is described for making single isomers of synthetic benzoprostacyclin analogue compounds, in particular the pharmacologically active 314-d isomer of beraprost. In contrast to the prior art, the method is stereoselective and requires fewer steps than the known methods for making these compounds.
