of N‐hydroxyaminoallyl radicals with nitrosoarenes. Our mechanistic analysis opposes a 5‐endo‐trig cyclization involved in the final ring‐closure step. To manifest the reaction utility, chemical elaborations of resulting isoxazolidinyl products into 2‐ or 3‐substituted quinoline N‐oxides and acyclic 1,3‐diamino‐2‐ols are also described.
