Total synthesis of (+)-erogorgiaene using lithiation-borylation methodology, and stereoselective synthesis of each of its diastereoisomers

A short (8 steps) synthesis of (+)-erogorgiaene in 44% overall yield from p-methylacetophenone is described. Key steps include lithiation/borylation- protodeboronation to build up the molecule and control the stereochemistry at C1 and C4. The C11 stereoch

Sesquiterpene constituents from the essential oil of the liverwort Plagiochila asplenioides

The essential oil of the liverwort Plagiochila asplenioides from two different locations in Northern Germany were investigated by chromatographic and spectroscopic methods. Seven compounds were isolated by preparative gas chromatography (GC) and their structures investigated by mass spectrometry (MS), NMR techniques and chemical correlations in combination with enantioselective GC. In addition to known constituents, aromadendra-1(10),3-diene, two aromatic sesquiterpene hydrocarbons, bisabola-1,3,5,7(14)-tetraene and bisabola-1,3,5,7-tetraene, three sesquiterpene ethers, muurolan-4,7-peroxide, plagiochilines W and X, in addition to ent-4-epi-maaliol, could be identified as natural compounds for the first time.

New Cadinene and Bisabolene Derivatives from the Essential Oil of Pulicaria gnaphalodes

From the essential oil of Pulicaria gnaphalodes growing near Tehran some new cadinene derivatives were isolated.The structures of 1,8-oxidocadin-4-enes (6, 7, epimers at C-10), 1(10),4-cadinadien-8α-ol (1), 4,10(14)-cadinadien- and 4, 10(14)-muuroldaien-8-ols (2-5) could be verified by their 1H- and 13C-NMR spectra.Furthermore, the 8α-epimer 9 of the known α-copaen-8β-ol (10), (Z)-γ-curcumen-12-ol (13a) and the esters (Z)-13b-e could be identified.Key Words: Pulicaria gnaphalodes / Compositae / 1,8-Oxidocadin-4-ene / Cadinadien-8-ols / α-Copaen-8-ol / γ-Curcumen-12-ol
