Tetrahedron Letters | 1999

Sandresolides A and B: novel nor-diterpenes from the sea whip Pseudopterogorgia elisabethae (Bayer)

Abimael D. Rodríguez; Catherine Ramirez; Ileana I. Rodriguez

Abstract A recent chemical study of the hexane extracts of Pseudopterogorgia elisabethae led to the isolation of two novel nor -diterpenes 1 and 2 , in addition to a known sesquiterpene 3 . The structures were established by spectroscopic and X-ray diffraction studies.

Tetrahedron Letters | 2000

Novel lactones from Pseudopterogorgia elisabethae (Bayer)

Abimael D. Rodríguez; Catherine Ramirez; Vilmarie Medina; Yan-Ping Shi

Abstract In addition to the previously reported terpenoids 1 and 2 , a chemical study of the hexane extracts of Pseudopterogorgia elisabethae led to the isolation of two novel skeletal lactones 3 and 4 . Their complete structures were established by interpretation of spectral data.
