Quickly FeCl3-catalyzed highly chemo- and stereo-selective [3 + 2] dipolar cycloaddition of aziridines with isothiocyanates†
Abstract
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.
