The synthesis of 1,2-diamines has been achieved through a single-step, tandem sequence involving Rh-catalyzed aziridination followed by NaI-promoted rearrangement to an isomeric cyclic sulfamide. Facile ring opening of these products in hot water and pyridine affords differentially protected vicinal diamines. Demonstration of the utility of this method for the syntheses of (±)-enduracididine and (
1,2-二胺的合成是通过单步串联序列实现的,该序列涉及 Rh 催化的氮丙啶化,然后是 NaI 促进的重排为异构环状磺酰胺。这些产物在热水和吡啶中容易开环,得到不同保护的邻二胺。强调了这种方法在 (±)-enduracididine 和 (±)-allo-enduracididine 合成中的效用。
