Abstract
Free-radical mediated stannylcarbonylation of azaenynes provides a general [n + 1]-type annulation approach leading to alpha-stannylmethylene lactams. The cyclization is unusual in its breadth, covering 4-exo, 5-exo, 6-exo, 7-exo, and 8-exo modes.
摘要
氮杂烯炔的自由基介导的锡羰基化反应提供了一种通用的[n + 1]型环化方法，可生成α-锡亚甲基内酰胺。这种环化反应在其广度上是不寻常的，涵盖了4-外向、5-外向、6-外向、7-外向和8-外向环化模式。
