摘要：

The sodium tungstate catalyzed oxidation of secondary amines with hydrogen peroxide gives the corresponding nitrones. Acyclic and cyclic nitrones can be obtained from secondary amines in a single step in good to excellent yields. The oxidation of secondary amines in the presence of alkenes gives isoxazolidines by 1,3-dipolar cycloaddition of nitrones. Introduction of a substituent at the 03B1-position of secondary amines can be performed upon oxidation of secondary amines and subsequent treatment with various nucleophiles. © 1990, American Chemical Society.
