[Chemical Constituents from Dalbergia cochinchinensis]
Objective:
To investigate the chemical constituents from the heartwood of Dalbergia cochinchinensis.
Methods:
Isolate and purify compounds by various column chromatographic methods. Spectral analysis were taken to identify the structures.
Results:
Elev- en compounds were isolated and identified as dibutyl terephthalate (1), medicarpin (2), pterostilbene (3), 6-hydroxy-2-(2-hydroxy-4- methoxyphenyl)-benzofuran (4), pterocarpol (5), butyl isobutyl phthalate (6), pterolinus B (7), methyl 4-hydroxybenzoate (8), ethyl 4- hydroxybenzoate (9),2-(2'-methoxy-4'-hydroxy)-aryl-3-methyl-6-hydroxy-benzofuran (10) and 6α-hydroxycyclonerolidol (11).
Conclusion:
Compounds 1 and 6~10 are isolated from Dalbergia genus for the first time, and compounds 2, 4 and 11 are isolated from this plant for the first time.

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,...
