Oxidative transformations of cembrane diterpenoids III. Epoxycembrenes [PDF]

open access: possibleChemistry of Natural Compounds, 1977
1. It has been established that the epoxidation of cembrene with perbenzoic and peracetic acids takes place stereospecifically at each of the trisubstituted double bonds with the formation of 4S,5R-, 7S,8S-, and 11S,12S-monoepoxycembrenes, the structures and absolute configurations of which have been established by spectral methods. 2.

Cembrane diterpenoids from the whole plant of Tournefortia sibirica

Tetrahedron Letters, 2020
Abstract Four new cembrane diterpenoids (1–4), along with four known compounds (5–8), were isolated from the whole plant of Tournefortia sibirica L. Their structures of these new compounds were elucidated mainly using NMR, HRESIMS and a modified version of Mosher’s method.

New Cembranes from Cleome spinosa [PDF]

open access: possibleJournal of Natural Products, 2003
Examination of the aerial portions of Cleome spinosa yielded five new cembranes, named cleospinols A (1), B (3), C (4), and D (5), and the 3'-hydroxy-iso-pentan-10-oate ester of cleospinol A (2). The cleospinols were determined to be derivatives of 10,13-dihydroxy-4,12-dimethyl-1-(1-methylethenyl)-11(E)-cyclotetradecene on the basis of spectroscopic ...

Labdane and cembrane diterpenoids from the oleoresin of thePicea ajanensis [PDF]

open access: possibleChemistry of Natural Compounds, 1981
From the oleoresin of the Yeddo spruce (Picea ajanensis Fisch.) have been isolated cis-abienol, isocembrol, geranyllinalool, epimanool, and labd-13E-ene-8α,15-diol. It has been established that the biosynthesis of isocembrol and epimanool in the Yeddo spruce is not accompanied by the formation of epimers of these compounds — 4-epiisocembrol and manool —
