Several β-aminothiols prepared from 3-piperideine and different thiiranes react by free radical reactio chemically initiated to yield exclusively 7-thia-1-azabicyclo (4,3,0) nonane derivatives. Even when this process is in competition with a radical addition on a terminal ethylenic chain, the bicyclic thiazolidine is always the major product.
由3-哌啶和不同的硫杂环丁烷制备的几种β-氨基硫醇通过化学引发的自由基反应进行反应,仅生成7-硫-1--1-氮杂双环(4,3,0)壬烷衍生物。即使该过程与末端烯键上的自由基加成竞争,双环噻唑烷也始终是主要产物。
