for dominoaddition/exo‐cycloisomerization of propargylic alcohols and tosyl isocyanate. In the presence of 2–5 mol% ruthenium complex, a range of terminal propargylic alcohols were reacted with tosyl isocyanate to furnish the corresponding oxazolidinone product exclusively in moderate to excellent yields. Mechanistic studies suggest that propargylic alcohol and tosyl isocyanate undergo addition firstly
