[Synthesis of "danshensu" derivatives]

This paper describes the synthesis of alpha-nicotinyloxy-beta-(substituted phenyl) propionic acid and alpha-(o-acetoxy)benzoyloxy-beta-phenyl propionic acid. They were obtained in six steps starting from benzaldehyde or substituted benzaldehyde. The preliminary pharmacological tests show that all compounds were effective for inhibition of rabbit platelet aggregation.
