and isomerization or rearrangement of N-sulfonylaziridines.2' However, there are some obvious drawbacks in these methods, such as long reaction times, unsatisfactory yields, formation of toxic by-products, the use of expensive and hazardous reagents as well as solvents, and tedious purification. Furthermore, some methods involve cumbersome and multi-step procedures. Therefore, it seems highly desirable
