Hydroxy-γ-sanshool was prepared with 19.5% overall yield through eight steps. Wittig reactions of ylides with ethyl 4-oxobut-2-enoate as well as (2E,4E)-hex-2,4-dienal were key steps to construct a carbon skeleton. The 2E,4Z-isomer in ethyl 8-hydroxyocta-
Members of the family of polyunsaturated amide compounds known as the sanshools are found in various Zanthoxylum species such as Sichuan (or Szechuan) peppercorns (huajiao). γ-Sanshool and hydroxy-γ-sanshool have been synthesized from simple building bloc
