Summary

2 new tetracarbocyclic sesterterpenes, isomers of the previously2 described scalaradial (1), have been isolated from the marine spongeSpongia nitens and their structures have been established to be2 and3; during the structural work, evidence on the stereochemistry of1,2 and3 has been obtained.
