  Photochemical conversion of xenicane into the crenulatane skeleton with diterpenoids of the brown seaweed Dictyota sp. from the coasts of Senegal

  摘要：

  UV irradiation of 4-hydroxydictyolactone (–)-1 in CDCl3 under N2 leads cleanly to 4-hydroxycrenulide (+)-2, reproducing what probably occurs under solar irradiation of the seaweed Dictyota sp. at low tide along the coasts of Senegal.
