Abstract

In the presence of LDA, 2-(trimethylsilylmethyl)pyridine reacts with p-substituted benzaldoxime methyl ethers to give stereoselectively trans-2-aryl-3-(2-pyridyl)aziridines and (Z)-1-amino-1-aryl-2-(2-pyridyl)ethenes. From the temperature-dependent 1H-nmr spectra of trans-2-phenyl-3-(2-pyridyl)aziridine, ΔF* was estimated to be about 14 kcal / mol at the coalescence temperature (Tc = 0 °C).
