Synthesis of Sesquiterpenes via silicon-guided rearrangement of epoxydecalins
2008
A survey of the rearrangement of methyldecalins via C-5 carbocation intermediates, with special attention to the silicon-guided rearrangement of epoxydecalins is provided. A TMS group properly positioned on either C-1 or C-9 promotes the acidic rearrangement of 10-methyl-4,5-epoxydecalins and 10-methyl-5,6-epoxydecalins with exclusive migration toward C-5 of the methyl or methylene groups linked directly to C-10. The application of this biomimetic approach to the synthesis of a number of spirocyclic and eremophilane sesquiterpenes is reported.

Ursane-type saponins from Zygophyllum cornutum
2013
Seven known ursane-type saponins were isolated from the methanolic extract of the whole plant of Zygophyllum cornutum Coss, and identified by 2D NMR spectroscopy and FAB-mass spectrometry. They are reported in this species for the first time and might be chemotaxonomically significant for the genus Zygophyllum.

Nostotrebin 6 Related Cyclopentenediones and δ-Lactones with Broad Activity Spectrum Isolated from the Cultivation Medium of the Cyanobacterium Nosto…
2020
Cyanobacteria are an interesting source of biologically active natural products, especially chemically diverse and potent protease inhibitors. On our search for inhibitors of the trypanosomal cysteine protease rhodesain, we identified the homodimeric cyclopentenedione (CPD) nostotrebin 6 (1) and new related monomeric, dimeric, and higher oligomeric compounds as the active substances in the medium extract of Nostoc sp. CBT1153. The oligomeric compounds are composed of two core monomeric structures, a trisubstituted CPD or a trisubstituted unsaturated δ-lactone. Nostotrebin 6 thus far has been the only known cyanobacterial CPD. It has been found to be active in a broad variety of assays, indi…

Certain D2-like dopamine receptor (DR) agonists are useful therapeutically as antiparkinsonian drugs, whereas D2-like DR antagonists or partial agonists are proven effective as antipsychotics. Two ...
