Root constituents of Cichorium pumilum and rearrangements of some lactucin-like guaianolides.
Two eudesmanolides, eight lactucin-like guaianolides and five phenolic compounds were isolated for the first time from roots of Cichorium pumilum, along with two previously reported eudesmane-type sesquiterpene lactones. Rearrangements of some lactucin-like guaianolides during isolation procedures were also discussed.
متن کاملA new general approach for the stereocontrolled synthesis of functionalised γ- and δ-lactams.
A new flexible approach for the stereoselective synthesis of substituted 1H-pyrrol-2(5H)-ones and 3,6-dihydro-1H-pyridin-2-ones has been developed. The general strategy employed the stereoselective reduction of a series of α,β-unsaturated ketones under chelation control to give the corresponding allylic alcohols. Overman rearrangement to install the key C-N bond followed by conversion to either...
متن کاملSynthesis of the tricyclic core of manzamine A.
An efficient synthetic approach to the core structure of the manzamine alkaloids is reported, particularly in relation to incorporating a one-carbon unit in ring B from which the aldehyde in ircinal A or the beta-carboline unit in manzamine A could potentially be generated. The key steps involve a Johnson-Claisen rearrangement, enolate alkylation, dithiane alkylation and a stereoselective intra...
متن کاملStereocontrolled synthesis of carbocyclic compounds with a quaternary carbon atom based on SN2' alkylation of γ,δ-epoxy-α,β-unsaturated ketones.
We developed a new method for stereoselective construction of an all-carbon quaternary stereogenic center on a carbocyclic ring based on regio- and stereoselective S(N)2' alkylation reactions of γ,δ-epoxy-α,β-unsaturated cyclic ketones. Treatment of the ketones, which were readily prepared in enantiomerically pure form by means of aldol condensations between 3-ethoxy-2-cycloalkenones and α,β-ep...
متن کاملStereoselective synthesis of a highly oxygenated decahydrocyclopenta[g]chromene derivative: the common tricyclic framework of leucosceptrine and leucosesterterpenone.
Stereoselective construction of the highly oxygenated decahydrocyclopenta[g]chromene skeleton, which is the tricyclic core of leucosceptrine, which possesses prolylendopeptidase inhibitory activity, and leucosesterterpenone, which exhibits anti-angiogenic activity, from Leucosceptrum canum, was achieved.
