The first synthesis of the shark repellent pavoninin-4, 3, was achieved in 12 steps with 21% overall yield from diosgenin, 8. Key reactions involve an efficient synthesis of the C-15α hydroxyl steroid from a C-16β hydroxyl steroid by an unexpected 1,2-tra

PAVONININS, SHARK-REPELLING AND ICHTHYOTOXIC STEROID N-ACETYLGLUCOSAMINIDES FROM THE DEFENSE SECRETION OF THE SOLE PARDACHIRUS PAVONINUS (SOLEIDAE)
Six steroid N-acetylglucosaminides, pavoninins-1 to -6, have been isolated from the defense secretion of the sole P.pavoninus guided by ichthyotoxicity and hemolytic activity, and their structures determined to be 1-6 by spectroscopic studies and chemical correlations.The pavoninins are considered to be the factors responsible for the repellent property of the sole against predatory fishes.
