Isolation of xestosterol esters of brominated acetylenic fatty acids from the marine sponge xestospongia testudinaria.

Journal of natural products

Pham NB, Butler MS, Hooper JN, Moni RW, Quinn RJ.
PMID: 10543913
J Nat Prod. 1999 Oct;62(10):1439-42. doi: 10.1021/np9901635.

The CH(2)Cl(2) extract of the marine sponge Xestospongia testudinaria inhibited [(3)H]DPCPX binding to rat-brain adenosine A(1) receptors. Bioassay-guided fractionation led to the isolation of a known brominated acetylenic fatty acid 1 as the active component. Also isolated were two...

Diterpenoids from euphorbia pithyusa subsp. cupanii.

Journal of natural products

Appendino G, Belloro E, Tron GC, Jakupovic J, Ballero M.
PMID: 10543901

The aerial parts of Euphorbia pithyusa subsp. cupanii collected in Sardinia afforded eleven novel diterpenoids belonging to the lathyrane (1a), premyrsinane (4a-g), and tigliane (5a-c) types. Compounds 4a-g and 5a are esters of two new parent alcohols, named premyrsinol...

Isolation of two highly methylated polyketide derivatives from a yew-associated penicillium species.

Dihydroartemisinic acid hydroperoxide (2) was isolated for the first time as a natural product from the plant Artemisia annua in a 29% yield. Its structure was identified by (1)H and (13)C NMR spectroscopy. Compound 2 is known as an...

Synthesis and absolute configuration of (S)-(-)- and (R)-(+)-2, 3-dihydro-2-(1-methylethenyl)-6-methoxybenzofuran.

Resolution of racemic 2,3-dihydro-2-carboxy-6-methoxybenzofuran (2) by recrystallizations of diastereomeric salts prepared with (S)-(-)-alpha-methylbenzylamine and (R)-(+)-alpha-methylbenzylamine gave the starting materials for the four-step total syntheses of (S)-(-)-2,3-dihydro-2-(1-methylethenyl)-6-methoxybenzofuran (1a) and (R)-(+)-2,3-dihydro-2-(1-methylethenyl)-6-methoxybenzofuran (1b). Their absolute configuration was established by chemical correlation.
