Clerodane Diterpenoids from Salvia splendens
Journal of Natural Products, 2006 Four new clerodane diterpenoids, salvisplendins A-D (1-4), have been isolated from an acetone extract of the flowers of Salvia splendens, together with an artifact (5), arising from salvisplendin D (4) by addition of diazomethane, and the already known clerodane olearin (6). The structures of the new compounds (1-5) were established mainly by 1D and 2D

Clerodane diterpenoids from Salvia blepharophylla
Phytochemistry, 1999 Abstract Two clerodane diterpenoids, blepharolides A and B, have been isolated from Salvia blepharophylla Brandegee ex Epling. Their structures were determined using a combination of one- and two-dimensional NMR techniques. The relative stereochemistry for blepharolide A was determined by X-ray diffraction.

Clerodane Diterpenoids from Croton crassifolius
Journal of Natural Products, 2012 Seven new clerodane diterpenoids (1-7) were isolated from roots of Croton crassifolius, along with six known compounds. The structures were elucidated by extensive spectroscopic methods (IR, UV, HRESIMS, 1D NMR, and 2D NMR), and the structures of 1, 3, 4, and 7 were confirmed by single-crystal X-ray diffraction analyses.

Neo-Clerodane Diterpenoids From Croton schiedeanus
Phytochemistry, 2003Two new neo-clerodane type furano diterpenoids were isolated from the aerial part of Croton schiedeanus, besides the clerodane diterpenes cis- and trans-dehydrocrotonin, previously isolated from other species of Croton. Structural elucidation was achieved on basis of extensive NMR experiments, including X-ray diffraction analysis and molecular ...

Neo-Clerodane Diterpenoids From Clerodendrum inerme
Phytochemistry, 2005Three neo-clerodane diterpenoids, inermes A, B and 14,15-dihydro-15 beta-methoxy-3-epicaryoptin, have been isolated from the hexane extract of the leaves of Clerodendrum inerme in addition to an epimeric mixture of 14,15-dihydro-15-hydroxy-3-epicaryoptin. Structures of these compounds have been elucidated on the basis of spectral studies.

Dimeric Clerodane Diterpenoids and Antiviral Constituents of Dodonaea viscosa
Bioorganic Chemistry, 2021Three unprecedented dimeric clerodane diterpenoids, dodovisdimers A-C (1-3), along with six known clerodane monomers (4-9), were isolated from Dodonaea viscosa. Compounds 1-3 may be biosynthetically formed via an intermolecular Diels-Alder [4+2] cycloaddition between the coexisting monomers 4-7.
