Novel hopanoid derivatives released by oxidation of Messel shale kerogen
摘要:
Oxidation of Messel share kerogen using ruthenium tetroxide yielded several series of hopanoid triterpenes which have been identified by synthesis. These compounds could originate from hopenes or hopanes of bacterial origin linked to the kerogen; their structures indicate that incorporation processes into macromolecular entities of their biological precursors must occur at a rather early stage of diagenesis.

In the presence of cuprous chloride, the representative biohopanoid la was smoothly converted by oxidation in pyridine into aldehydes, ketones and carboxylic acids with the same skeletons as those of molecular fossils ubiquitously found in the organic matter of sediments.
