The present research has been carried out in two stages. In the first stage of research the reaction of interaction of allyl acetate with tricycle[5.2.12.5.1.0^2.6]deca-3,8-diene with allylacetate in the presence of catalyst nano-TiO₂ (20–22 nm) have been studied, as the result 8-acetoxymethyltetracyclo [4.4.1^2.5.1^7.10.0^1.6]dodec-3-ene with yield of 77.4% have been synthesized.  In the second stage of research the addition reaction of saturated aliphatic monobasic acids С₁-С₅ to synthesized unsaturated monoesters in the presence of catalyst (BF₃-OEt₂) has been proceeded and corresponding diesters have been synthesized with yield 75.5–90.6%, which can be used as additives for softening compositions of perfume components.
