  由齐墩果酸和山梨酸部分合成C环衍生物。通过化学和光化学异构化过程形成数个三烯系统

  摘要：

  从橄榄油压榨固体废物中所含的齐墩果酸半合成了一些在C环上改性的三萜类化合物。齐墩果酸和山lin酸的相应酯使产物具有二烯体系，其通过电环反应产生类似于维生素原D 2的油烯酮。这些化合物的化学和光化学异构化反应产生了两种不同的三烯，其结构与速甾醇和维生素D 2相似。

• Degradation of triterpenic compounds from olive-pressing residues. Synthesis of trans-decalin type chiral synthons

  Three seco-Gring triterpenic compounds were obtained from oleanolic or maslinic acids from olive-mill solid wastes by photochemical and chemical reactions. From these oleantriene compounds, different remarkable sesquiterpene and nor-sesquiterpene fragments such as 3beta-hydroxydrimenol (13) and epoxydecalone (16) were achieved through oxidative cleavages of the double bonds in the opened Gring.

• Oxidation of several triterpenic diene and triene systems. Oxidative cleavage to obtain chiral intermediates for drimane and phenanthrene semi-synthesis

  An exhaustive oxidation study has been made with ozone, MCPBA and/or NaIO4/RuCl3 of several triterpenic diene and triene compounds from oleanolic and maslinic acids obtained from olive-oil pressing. Through several oxidative cleavages of the opened C-ring of these oleantrienes, different significant decalin-type chiral synthons were achieved. These sesquiterpene and nor-sesquiterpene products are of great interest because by means of several simple reactions they could lead to drimane, phenanthrene and tricyclic triterpene compounds.
