The reaction of silyl nitronates and enol diazoacetates affords N‐silyloxy‐3,6‐dihydro‐2H‐1,2‐oxazines as a new type of nitroso acetal. The scope of the reaction was established. Quantum chemical calculations and kinetic data allowed the nitrogen inversion barrier in the target nitroso acetals to be determined.
