Abstract

The results of studies of some terpenoids, alkaloids and phenolic derivatives isolated from Siberian plants are summarised. The structures of the compounds studied are presented and the chemical transformations of the available terpenoids and alkaloids are considered. Examples of practical application of natural compounds and their derivatives are given.

Abstract

The stereoselective synthesis of two phosphorus-containing derivatives of the known guaianolide arglabin was carried out for the first time. The molecular structures of these products were established based on the spectroscopic data and the results of X-ray diffraction analysis of one of these compounds.

Abstract

The reaction of sesquiterpene lactone achillin with chlorine in methanol afforded four products,viz., two monochlorides and two dichlorides. One of these monochlorides is an intermediate in the formation of both dichlorides. The structures of the reaction products were established by two-dimensional NMR spectroscopy. The structure of one of the products was also established by X-ray diffraction analysis.

Abstract

A new diterpene derivative, 18-succinyloxyabieta-8,11,13-triene, was isolated from the acidic fraction of the extract from wood greens of a Siberian fir. The chemical structure of the molecule was established on the basis of spectroscopy and confirmed by partial synthesis from abieta-8,11,13-trien-18-ol.
