摘要
Four new closely related vicinal diols, (1R,2R)-1-(5-(pent-4-en-l-yl)faran-2-yppropane-1,2-diol (1), (1S,2R)-1-(5(pent-4-en-l-yl)furan-2-yl)propane-1,2-diol (2), (1R,2R)-1-(5-pentylfuran-2-yl)propane-1,2-diol (3) and (1R,2S)-1-(5-pentylfuran-2-yl)propane-1,2-diol (4), were isolated from the cultures of the fungus Ceriporia alachuana. Their structures and absolute configurations were totally determined by spectroscopic means, chemical method (forming di-O-isopropylidene derivative) and Mo-2(OAc)(4) induced circular dichroism (ICD) experiments.
