摘要
从阿拉华蜡孔菌发酵液中分离鉴定四个呋喃邻二醇,1R,2R-1-[5-(戊-4-烯-1-基)呋喃-2-基]丙烷-1,2-二醇(1),1S,2R-1-[5-(戊-4-烯-1-基)呋喃-2-基]丙烷-1,2-二醇(2)、1R,2R-1-[(5-戊基)呋喃-2-基]丙烷-1,2-二醇(3)和1R,2S-1-[(5-戊基)呋喃-2-基]丙烷-1,2-二醇(4).综合运用波谱分析(1D、2DNMR,HRMS)、化学法(异丙叉衍生物)和乙酸钼二聚体[Mo_2(OAc)_4]诱导CD谱等方法确定了化合物1~4的绝对构型.
Four new closely related vicinal diols,(1R,2R)-1-(5-(pent-4-en-1-yl)furan-2-yl)propane-1,2-diol(1),(1S,2R)-1-(5-(pent-4-en-1-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.
