Abstract:
Two new spirobenzofuranoid dibenzocyclooctadiene lignans, kadsulignans O (1) and P (2) were isolated from the stems of Kadsura oblongifolia, together with five known same type lignans, kadsulignans C (3), E (4), F (5), G (6), and heteroclitin J (7). Their structures were elucidated on the basis of spectral evidences and comparisons with literatures. Compounds 3-7 were isolated from this plant for the first time.

[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...
