Generation and cycloaddition of less- or non-stabilized azomethine ylides, or nitrile ylide equivalents, via unprecedented 1,4-stannatropy of N-(tributylstannylmethyl)thioamides were achieved. The reactions with dipolarophiles, such as electron-deficient alkenes and alkynes, afforded corresponding pyrrolidine and pyrrole derivatives effectively.
通过空前的N-(三丁基锡烷基甲基)硫代酰胺的1,4-苯乙烯基转移反应,实现了稳定性更差或不稳定的甲亚胺基亚胺或腈基当量的生成和环加成。与偶极亲电子的反应,例如缺电子的烯烃和炔烃,有效地提供了相应的吡咯烷和吡咯衍生物。
