isolated from the gorgonian coral Rumphella antipathies, two new compounds, (1R,2S,5S,8R,9S,10R)-2-methoxyclovane-9,10-diol (5) and (1S,2S,5S,7R,8R,9R)-2-methoxyclovane-7,9-diol (6), hydroxylated in positions not easily accessed by classic synthetic chemistry, and clovanodiols 3 and 4. P. minioluteum is able to selectively transform methoxyclovanol (1) into clovanodiols 3 and 4 and, in turn, lactone 8, the
在这里,我们描述了丝状真菌Pestalotiopsis palustris和Penicillium minioluteum对丁香衍生物的生物转化,以及后者在合成和确定rumphellclovane A(2)的绝对构型中的应用。甲氧环戊醇(1)是一种植物病原体灰葡萄孢的生长抑制剂,被P. palustris代谢产生了rumphellclovane A(2),这是一种最近从高哥氏珊瑚Rumphella抗病性中分离得到的天然化合物,这是两种新化合物,(1 R,2 S,5 S,8 R,9 S,10 R)-2-甲氧基环戊烷-9,10-二醇(5)和(1 S,2 S,5 S,7 R,8 R,9 R)-2-甲氧基环戊烷-7,9-二醇(6),在经典合成化学不易接近的位置羟基化,以及邻苯二酚3和4。小白僵菌能够选择性转化甲氧基环戊醇(1)成氯丁二醇3和4,继而又变成内酯8,内酯8是上述多普勒环戊烷A(2)的合
