Diarylheptanoids from Myrica arborea

Phytochemistry, 2000
Investigations of the stem and root bark of Myrica arborea (Myricaceae) have yielded two novel diarylheptanoids, myricarborin and 11-O-beta-D-xylopyranosylmyricanol along with the known myricanol and 5-O-beta-D-glucopyranosylmyricanol. The structures of the novel compounds were determined by spectroscopic methods.

Diarylheptanoids of Centrolobium species

Phytochemistry, 1970
Abstract The heartwoods of two Centrolobium species (Leguminosae) were examined. C. robustum Mart. was found to contain piceatannol, (-)-centrolobine (VIIa), (-)-de- O -methylcentrolobine (VIIb) and (-)-centrolobol (VI). C. tomentosum Benth. was found to contain (+)-centrolobine (IXa), (+)-de- O -methylcentrolobine (IXb) and (+)-centrolobol ...

Synthesis of a diarylheptanoid, (+)-centrolobine

Tetrahedron: Asymmetry, 2010
A chiron approach for the total synthesis of (+)-centrolobine has been described from the commercially available aldehyde 3 employing an acid-catalyzed stereoselective formation of tetrahydropyran ring as the key step. The desired molecule was accomplished in eight steps with 62% overall yield.

Synthesis of gingerol and diarylheptanoids

Tetrahedron: Asymmetry, 2011
Abstract The synthesis of gingerol 1 and related compounds 2 – 5 along with diarylheptanoids 6 – 8 has been accomplished using a Keck allylation, Crimmins’ aldol reaction, aldehyde coupling with acetylene, and chelation controlled reductions as the key reactions.

New Diarylheptanoids and Diarylheptanoid Glucosides from the Rhizomes of Tacca chantrieri and Their Cytotoxic Activity

Journal of Natural Products, 2002
Two new diarylheptanoids (1, 2) and seven new diarylheptanoid glucosides (3-9) were isolated from the rhizomes of Tacca chantrieri. Their structures were determined by spectroscopic analysis, including 2D NMR data, and the results of hydrolytic cleavage.

Diarylheptanoids from Alpinia officinarum

Journal of Asian Natural Products Research, 2006
A new diarylheptanoid, along with five known diarylheptanoids, was isolated from the rhizomes of Alpinia officinarum (Zingiberaceae). The structure of the new compound was determined to be trans,trans-1(3'-methoxy-4'-hydroxyphenyl)-7-phenyl-5-ol-4,6-dien-3-heptanone on the basis of spectral and chemical evidence.
