  Cedrelone 的光氧化，来自香椿的四萜类化合物¶

  摘要：

  摘要 Cedrelone 是一种四降三萜类化合物，通过紫外线光解产生真正的光氧化产物 3 [14 β,15β,22β,23β-diepoxy-6-hydroxy-1,5,20(22)-meliatriene-2,7,21-trione ] 其结构已通过 NMR 研究确定并通过 X 射线晶体学证实，以及产物 4 [14 β,15β-epoxy-6,23-dihydroxy-1,5,20(22)-meliatriene-2,7, 21-trione]。添加玫瑰红会增加光氧化速率，而 DABCO 会降低光解速率，证明单线态氧参与了光氧化。两种光产品都表现出拒食活性。

  Ethylenediamine: an effective reagent for deacetylation of natural products

  摘要：

  The use of ethylenediamine in methanol is described for the selective cleavage of the acetate group in nimbin (1) to 6-deacetyl nimbin (1a) under microwave irradiation. This method enables to deacetylate without affecting other functional groups such as ,-unsaturated ketone, ester, ether, etc. in certain tetranortriterpenoids and other acetate-containing natural compounds.
