Dependence of the stereochemistries of intramolecular [8 + 2] cycloadditions of alkenylheptafulvenes on tetraenophile stereochemistry was written by Liu, Ching Yang;Houk, K. N.. And the article was included in Tetrahedron Letters in 1987.Synthetic Route of C6H11BrO2 This article mentions the following:
Intramol. [8 + 2] cycloaddition reactions of (cyanoalkenyl)heptafulvenes I (n = 2, R = H, R1 = CO2Et; n = 2, R = CO2Et, R1 = H) give as primary products carbethoxycyanotricyclotridecatrienes II and III, resp. I (n = 3, R = H, R1 = CO2Et) gives cis– and trans-tricyclotetradecatrienes IV. The observed stereochem. is discussed based on secondary orbital interactions. In the experiment, the researchers used many compounds, for example, 2-(3-Bromopropyl)-1,3-dioxolane (cas: 62563-07-9Synthetic Route of C6H11BrO2).
2-(3-Bromopropyl)-1,3-dioxolane (cas: 62563-07-9) belongs to dioxole derivatives. Dioxoles, particularly fluorinated dioxoles, are used as co-monomers to make polymers that find use in forming protective coatings for chemical resistance. 1,3-Benzodioxole can be synthesized from catechol with disubstituted halomethanes.Synthetic Route of C6H11BrO2
