Conclusions Simple routes for the synthesis of (2RS, 8R)-(–)-2-propionoxy-8-methyldecane (I) the pheromone of the leaf beetleDiabrotica virgifera virgifera — from chiral monofunctional synthons, obtained from the available (S)-(+)-3,7-dimethyl-1,6-octadiene, were developed.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 9, pp. 2080–2083, September, 1987.It corresponds to Communication 4 in the series Terpenes in Organic Synthesis. For the preceding Communication, cf. [1]. 相似文献

The new alkaloid folidine with mp 148–149°C (acetone-petroleum ether) has been isolated from the epigeal part of the plantHaplophyllum foliosum Vved., and on the basis of spectral characteristics and passage to the known alkaloid folifidine (8-hydroxy-4-methoxy-1-methyl-2-quinoline) its structure has been established as 4-methoxy-1-methyl-8-(2-oxo-3-methylbutoxy)-2-quinolone.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek, Tashkent.

Two trail attractants for the termiteR. lucifugus have been isolated from the plantZizyphus jujuba: - and -bisabolenes. The threshold concentrations of the actions of these substances amounts to 10–9 g/liter. -Bisabolene in the range of concentrations of 1–10–6 g/liter is a powerful repellant for termites.Institute of Physiologically Active Substances, Academy of Sciences of the USSR, Chernogolovka.

The structure of an extracellular mannan formed by the yeastBullera tsugae has been studied. It has been shown that the repeating unit of this polysaccharide contains -(13)- and -(14)-bound D-mannopyranose residues in equimolar ratio. A comparison has been made of the polymer under investigation with the extracellular mannan from a yeast of the genusRhodotorula.
