Semisynthesis and biological evaluation of abietane-type diterpenes. Revision of the structure of rosmaquinone.

30 Jul 2009 The new aromatic diterpenes 7beta-O-benzylrosmanol (3), 7beta-O-benzyl-11,12-di-O-methylrosmanol (4), and 7alpha-thiophenylcarnosic acid (5) have been obtained by partial synthesis from carnosol (1), an abundant natural diterpene present in Salvia ... Read more...

A new rearranged abietane diterpene and other constituents from Clerodendrum philipinum.

27 Feb 2009 From the methanolic extract of the roots of Clerodendrum philipinum, a new rearranged abietane diterpene (1) and eight known compounds were isolated by various chromatography methods. Their structures were identified by means of spectroscopic ... Read more...

ent-Abietane and ent-kaurane diterpenoids from the roots of Suregada glomerulata.

21 Feb 2009 Twelve ENT-abietane and ENT-kaurane type diterpenoids, 1- 12, including five new compounds 1- 5, were isolated from the roots of Suregada glomerulata. The structures of the new compounds were elucidated on the basis of 1D and 2D NMR and other ... Read more...
