  The role of the 12-carboxylic acid group in the spontaneous autoxidation of dihydroartemisinic acid

  摘要：

  Three of the four steps in the slow spontaneous autoxidation of dihydroartemisinic acid to artemisinin ('ene-type' reaction of molecular oxygen with the Delta(4.5) double bond, Hock cleavage of the resulting tertiary allylic hydroperoxide, oxygenation of the enol product from Hock cleavage and cyclization of the resulting vicinal hydroperoxyl-aldehyde to the 1,2,4-trioxane system of artemisinin) are shown to be assisted by the proximity of the 12-carboxylic acid functional group in dihydroartemisinic acid to the functional groups participating in these reactions.

• Biomimetic synthesis of arteannuin h and the 3,2-rearrangement of allylic hydroperoxides
  作者：Lai-King Sy、Koon-Sin Ngo、Geoffrey D. Brown

  The acyl endoperoxide arteannuin H, recently reported as a novel natural product from Artemtsia annua, has been obtained in two steps from the photooxidation of dihydroartemisinic acid, thereby confirming biogenetic speculation regarding its derivation from a secondary allylic hydroperoxide. The little studied 3,2-rearrangement reaction of such allylic hydroperoxides is also discussed.

  Photooxidation of 4-amorphen-11-ol (1), recently reported as one of the major sesquiterpene natural products from the medicinal plant Fabiana imbricata, results in three allylic hydroperoxides 6, 9 and 10, which are expected from the “ene-type” reaction of molecular oxygen with the tri-substituted double bond in 1. The tertiary allylic hydroperoxide 6 undergoes carbon-carbon bond cleavage and a second

  The total proton and carbon‐13 NMR assignments of quinghaosu I, II and V isolated from Artemisia annua cultivated in Brazil and of the synthetic derivatives quinghaosu alkene, ketone and epoxy are reported. The conformations and conformational equilibria of these compounds in solution were obtained from the spectral data and molecular mechanics calculations.
