Abstract

Radical cyclization of the 1,6-hexadiene moiety in 2,2-diallyl substituted methyl or benzyl dihydrobetulonates initiated by Fe(NO3)3·9H2O in the presence of FeCl3 or LiCl gave hitherto unknown spirocyclic compounds in which ring A of the lupane triterpenoid at position C-2 is spiro coupled with a vicinally substituted nitromethyl- and chloromethylcyclopentane. Based on a quantum-chemical assessment of the energy characteristics of this reaction, the most probable configurations of the chiral atoms in the spirocyclopentane ring were determined for the major diastereomers isolated in individual form.

Abstract

Partial ozonolysis of 1-methyl-1Z,5Z-cyclooctadiene gives 8-oxo-4Z-nonene-1-al, which is converted to Lepidoptera pheromones after subsequent transformations.

Abstract

Partial ozonolysis of 1Z,5Z-cyclooctadiene followed by selective transformation of ester and acetal groups in methyl ester of 8,8-dimethoxy-4Z-octen-1-oic acid, and by a two step elongation of carbon chain of the latter by means of tosyloxy groups teplacement under action of decyl- and pentyl magnesium bromides leads to musculare - the sex pheromone of house fly.
