Abstract: A new dihydrobenzofuran, ( S )-2-(3′-hydroxyisoprop-1′- enyl )-2 , 3-dihydrobenzofuran-5- carbaldehyde ( 1) was isolated from the culture broth of Bondarzewia berkeleyi together with two known dihydrobenzofurans (2 - 3) and one known benzofuran (4) . Their structures were elucidated on the basis of spectroscopic analysis including 2D NMR experiments , and they were isolated for the first time from the fungi of the genus Bondarzewia .
