Facile synthesis of aziridines from imines and diazoesters or aldehydes, amines, and diazoesters using a catalytic amount of lanthanide triflate

Article abstract of DOI:10.1246/cl.1998.685

In the presence of a catalytic amount of lanthanide triflate (Ln(OTf)₃), imines reacted with ethyl diazoester in hexane at room temperature to afford the corresponding aziridines in high yields with high diastereoselectivities. Based on these r
