SYNTHESIS OF ISOMERICALLY PURE VINYLCHLORIDES BASED ON ALKYLATION OF ACTIVE METHYLENIC COMPOUNDS BY INDIVIDUAL ISOMERS OF 1,3-DICHLOROPROPENE
Effective synthesis methods of stereochemically pure vinylchlorides based on the monoalkylation of 1,3-dicarbonyl compounds by individual isomers of 1,3-dichloropropene followed by Krapcho decarboxylation were developed. Its practical purchase was shown by stereodirected synthesis of (4 Е )-tridec-4-en-1-ylacetate - the sex pheromone of tomato pinworm ( Keiferia lycopersicella ) and (4 E,6 Z )-hexadeca-4,6-dien-1-ol and its acetate - the sex pheromone of moth ( Stathmopoda masinissa ).
