Allylic and homoallylic esters of thioxoacetic acid (1b), when generated by thermal cleavage of various Diels–Alder adducts in solution (111 °C) or by flash vacuum pyrolysis (600 °C), undergo intramolecular ‘ene’ reactions with C–C bond formation.
硫代乙酸的烯
丙酯和均烯丙基酯(1b),是通过溶液中的各种Diels-Alder加合物的热裂解(111°C)或通过快速真空热解(600°C)生成的,会与C–C发生分子内“烯”反应键的形成。
