Iridoide, X: Stereospezifische Synthese von Iridoid‐α‐glucosiden
Chemische Berichte, 1978Iridoids, X: Stereospecific Synthesis of Iridoid‐α‐glucosidesTreatment of the iridoidaglycone 3 with 1,2‐anhydro‐α‐D‐glucopyranose triacetate (Brigls anhydride, 4) in the presence of a trace of boron trifluoride/ether led stereospecifically to the α‐glucosides 7, 8, and 9, with 38% yield. In an analogous reaction 10 was formed from 2.

Iridoids From Loasa Acerifolia
Phytochemistry, 1998In the course of preliminary chemotaxonomic studies on Loasaceae from South and Central America, 30 species from 6 genera were screened by chromatographic means. From the aerial parts of Loasa acerifolia Dombey, the novel trimeric and dimeric iridoid glucosides acerifolioside and tricoloroside methyl ester, consisting of loganin and secoxyloganin ...

Synthetic Aspects of Iridoid Chemistry
2000The aim of the present review is to cover developments in the chemistry of iridoids and related compounds during the last decade. In order to be able to give a broad, but still comprehensive presentation of this vast area some limitations to the subject were necessary. Accordingly, the chemotaxonomic importance and biosynthesis studies of iridoids will
