摘要：

The Heck reaction is a more efficient and reliable method than previous ones for introducing a C3 unit at the benzyl position for the synthesis of Beraprost. Especially, trialkylated long-chain amines such as (n-C8H17)(3)N and (n-C12H25)(3)N resulted in good yields. This development will be used for the industrial synthesis of Beraprost.
