摘要:
An efficient iron porphyrin Lewis acid-catalyzed cycloaddition of aziridines with aldehydes has been developed to provide oxazolidines with high regio- and diastereoselectivity. The cycloaddition proceeds in toluene with 1 mol % of the iron catalyst at 25 degrees C. A theoretical study and synchrotron-based X-rabsorption fine structure measurements provided fundamental insights into the aziridine iron porphyrin complex, which is the key intermediate for the generation of the 1,3-dipole synthon.
