title: On the structure of aspongopusin recently isolated from Aspongopus chinensis.
abstract: The 2,5-disubstituted oxazole recently proposed for aspongopusin, a natural product isolated from Aspongopus chinensis, was synthesized through an unambiguous route. The synthetic sample showed (1)H and (13)C NMR entirely different from those in the literature, revealing that the initially assigned structure was incorrect. The spectroscopic data for the given structure are thus made available for the first time.
