Oxygen‐substituted isocyanates (O‐isocyanates) are rare isocyanates with a reported propensity to trimerize, a side‐reaction that severely limited their use in synthesis. Herein, the development of blocked (masked) O‐isocyanate precursors that form this reactive intermediate in situ provide controlled reactivity, allowing the first examples of cascade reactions involving O‐isocyanates. Complex hydroxylamine‐derived
