The biosynthesis of blazeispirol A, an unprecedented skeleton, was investigated by feeding 13 C-labeled acetates, propionate and methionine, to the growing cultures of Agaricus blazei (Agaricaceae). 13 C NMR spectral analysis demonstrated the mevalonate origin of the spiroacetal moiety and the dihyd

Blazeispirol A, an unprecedented skeleton has been isolated from the cultured mycelia of Agaricus blazei(Agaricaceae). Its structure was elucidated to be the previously unknown spiro [4,10b-ethanonaphtho[l,2b]pyran-2,2'-furan] skeleton which was established by extensive 1D and 2D NMR spectral data a

Two novel blazeispirol derivatives, blazeispirol X and Y, have been isolated from the cultured mycelia of Agaricus blazei (Agaricaceae). The structures were elucidated to be (20S,22S,23R,24S)-1 (1036) abeo-14b,22:22,25-diepoxyergosta-5,7,9,11-tetraene-3a,23-diol and (20S,22S,23R,24S)-14b,22:22,25-di
