Structure of sporogen-ao 1, a sporogenic substance of aspergillus oryzae

Abstract A sporogenic substance, sporogen-AO 1, isolated from the culture broth of Aspergillus oryzae (NOY-2) has been shown to have the structure 1. The structure was elucidated using spectroscopic methods, especially by long range selective proton decoupling in the gated decoupled 13 C nmr spectrum and with difference nuclear Overhauser effect techniques.
