cis‐1‐tosyl‐2‐tosyloxymethyl‐3‐(trifluoromethyl)aziridine was developed, starting from 1‐ethoxy‐2,2,2‐trifluoroethanol, involving imination, aziridination, ester reduction, hydrogenation, and N‐,O‐ditosylation steps. Further syntheticelaborations revealed a remarkable difference in the reactivity of cis‐1‐tosyl‐2‐tosyloxymethyl‐3‐(trifluoromethyl)aziridine with respect to aromatic sulfur and oxygen nucleophiles,
