A novel strategy involving visible-light-induced functionalization of alkenes for the synthesis of substituted aziridines was developed. The readily prepared N-protected 1-aminopyridinium salts were used for the generation of N-centered radicals. This approach allowed the synthesis of aziridines bearing various functional groups with excellent diastereoselectivity under mild conditions. Moreover, this

A FeCl3-catalyzed [3 + 2] cycloaddition reaction of aziridine with isothiocyanate was developed. The cycloaddition reaction was completed in two minutes with high chemoselectivity, stereoselectivity. 15 (tosylthiazolidin-2-ylidene)anilines were obtained with moderate to excellent yields.
