TL;DR: Anionic macroporous resin in non-aqueous medium was used with success in this article for separation of the acid fraction of Copaifera multijuga (Copaiba oil), rich in labdanic diterpenes and for the methanolic extract of Croton cajucara (acetyl aleuritoric acid).

TL;DR: In this article, the dephosphorylation reactions of the organophosphates diethyl 2,4-dinitrophenyl phosphate (DEDNPP) and dimethyl 4-nitrophenymethyl phosphate (methyl paraoxon) by oxime 2-(hydroxyimino)-N-phenyl-acetamide (Ox 1) were reported.
Journal ArticleDOI
Two monoisoprenylated flavonoids from Vellozia graminifolia
TL;DR: In this article, a mixture of two monoisoprenylated flavonols velloquercetin 3,3,4,4′-dimethyl ether (Vellozia graminifolia) was isolated and characterized from the hexane whole plant extract.
Journal ArticleDOI
Minor cleisthantane and tetranorfriedolabdane from Vellozia flavicans
TL;DR: In this paper, six diterpenes with the cleistanthane skeleton have been identified from Vellozia flavicans, three of which are reported as natural products.
Journal ArticleDOI
An investigation of a palladium catalysed biaryl synthesis of pyrrolophenanthridine derivatives. Extension of the Heck reaction
TL;DR: In this paper, N-Benzylisatin derivatives have been found to readily undergo cyclisation via hydrogen halide elimination in a biaryl synthesis reaction when using palladium catalysts, in the absence of phosphine ligands, to yield oxopyrrolo[3,2,1-de]phenanthridine derivatives.
