Vicinal Diamination of Alkenes under Rh-Catalysis
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 (±)-allo-enduracididine
is highlighted
