Hygroline derivatives from schizanthus tricolor and their anti-trypanosomatid and antiplasmodial activities
(Elsevier, 2021)
Chemical investigation of the alkaloid extract of the aerial parts of Schizanthus tricolor led to the targeted
isolation of 26 hygroline derivatives of which 20 were fully characterized. They have not yet been described ...
Efficient synthesis of a new aminoazasugar and dihydroxyprolines from an endocyclic enecarbamate

Asymmetric construction of substituted pyrrolidines via 1,3-dipolar cycloaddition of azomethine ylides and chiral acrylates derived from biomass
(ElsevierAmsterdam, 2014-04)
The first application of chiral auxiliaries synthesized from levoglucosenone (a biomass-derived anhydrosugar) in asymmetric 1,3-dipolar cycloaddition reactions of azomethine ylides is herein reported. The corresponding ...

Antifungal amides from Piper arboreum and Piper tuberculatum
(Elsevier B.V., 2002-03-01)
In continuation of our study of the Piperaceae we have isolated several amides, mainly those bearing isobutyl, pyrrolidine, dihydropyridone and piperidine moieties. Bioactivity-guided fractionation of extracts from leaves ...
