  Sex Pheromones of the Hair Crab Erimacrus isenbeckii. II. Synthesis of Ceramides

  摘要：

  To confirm their structures and to assess the pheromonal activity, novel ceramides, possible sex pheromones of the hair crab Erimacrus isenbeckii, were synthesized from D-galactose. The synthetic ceramides were identical with the natural ceramides.
