## Abstract The regio‐ and stereoselectivity of the 1,3‐dipolar cycloaddition reaction of 1‐aryl‐__N__‐methyl‐2‐(1__H__‐azol‐1‐yl)ethanimine __N__‐oxides 6 to monosubstituted olefins 7 were investigated. The reaction is regioselective, leading to the corresponding C‐5 substituted isoxazolidines 8/9
