| Abstract: | The occurrence of a novel class of tetracyclic triterpanes in petroleum is reported. These compounds presumably derive from pentacyclic hopanes by ring C opening. The identification of one C30H54 8,14-seco-hopane has been effected by means of comparison with a mixture of synthetic isomeric compounds. Homologous seco-hopanes parallel the distribution of hopanes between C27 and C30. |
