Article Synopsis
- - The study introduces a new method for oxyaminating alkenes using sulfonamides, facilitated by WODipic(HO), resulting in high yields and selectivity for various types of alkenes.
- - A detailed catalytic cycle is proposed, which includes the formation of a tungstenooxaziridine complex as the active catalyst, with hydrolysis of a tungstenooxazolidine intermediate being the slowest step.
- - Initial experiments on kinetics and competition support the validity of the proposed mechanism behind this oxyamination reaction.
Herein we report the zirconooxaziridine promoted aziridination of alkenes using chloramine T as the quantitative source of N. The reaction works with high yields, diastereoselectivities and stereospecificity for a wide variety of substituted alkenes. A potential mechanism involving the formation of a zirconooxaziridine complex as the active catalyst has been proposed and initial mechanistic data would indicate that a highly associative mechanism is the predominant pathway for this transformation.
