Abstract:
From the dried roots of Euphorbia fischeriana, seven new diterpenoids, 3alpha,17-dihydroxy-ent-pimara-8(14),15-diene (1), 7beta,11beta,12beta-trihydroxy-ent-abieta-8(14),13(15)-dien-16,12-olide (2), 17-acetoxyjolkinolide B (3), 13beta-hydroxy-ent-abiet-8(14)-en-7-one (4), 12-deoxyphorbaldehyde-13-acetate (5) 12-deoxyphorbaldehyde-13-hexadecacetate (6), and 12-deoxyphorbol-13-(9Z)-octadecanoate-20-acetate (7), and two known compounds, 12-deoxyphorbol-13-decanoate (8) and prostratin (9), were isolated. The structures of the new compounds were elucidated on the basis of spectroscopic analysis. The structure of compound 1 was confirmed by single-crystal X-ray crystallography. Compounds 3 and 8 exhibited potent cytotoxic activity to Ramos B cells with IC50 values of 0.023 and 0.0051 microg/mL, respectively.

Stability of Conjugated Dienes
A comparison of the enthalpies of hydrogenation of dienes reveals that conjugated dienes release less heat on hydrogenation, rendering them more stable than their nonconjugated analogs.
Diels–Alder Reaction: Characteristics of Dienes
Characteristics of the diene
Conformation
The simplest example of a diene is 1,3-butadiene, an acyclic conjugated π system. At room temperature, the molecule exists as a mixture of s-cis and s-trans conformers by virtue of rotation around the carbon–carbon single bond. Although the s-trans isomer is more stable, the...

[4+2] Cycloaddition of Conjugated Dienes: Diels–Alder Reaction
Structure of Conjugated Dienes
Conjugated dienes are compounds characterized by the presence of alternating double and single bonds. In a conjugated system like 1,3-butadiene, the unhybridized 2p orbital on each carbon overlaps continuously, allowing the π electrons to be delocalized across the entire molecule. In contrast, this type of overlap does not occur in cumulated and isolated dienes, such as 2,3-pentadiene and 1,4-pentadiene, respectively. Instead, the π electrons remain localized between the double...
