Triterpene glycosides ofAstragalus and their genins. XVI. Cyclogaleginosides A and B fromAstraglus galegiformis

The reductive amination of d-fenchone by aliphatic nitriles has been studied. A probable reaction pathway is suggested, and the stereochemical composition of the products has been determined. It has been established with the aid of¹³C NMR that the reaction forms a mixture of isomeric optically active N-alkyl-1,3,3-trimethylbicyclo[2.2.1]hept-2-ylamines with a 3:1 ratio of endo and exo isomers. The absolute configurations of the amines synthesized have been determined.Institute of Physical Organic Chemistry, Academy of Sciences of the Belorussian SSR. Minsk.

Micranthoside — A new glycoside fromEupatorium micranthum

From the epigeal parts of the plantEupatorium micranthum Less., introduced into the Sukhumi Botanical Garden, a new glycoside has been isolated which has been called micranthoside and which has the structure of 4′,5-di-0-β-glucosyl-7-0-methyldihydrokaempferol or 4′,5-di-0-β-D-glucosyl-7-0-methylaromadendrin.
