## Abstract 1,3‐Dipolar cycloaddition (1,3‐DC) between acryloyloxazolidone **1** and diphenylnitrone **2** was catalysed by complexes of three (4__R__)‐phenylbis(oxazolines) [box = bis(oxazolines)] − either 5‐unsubstituted (**8a**), or 4,5‐__cis__‐ and ‐__trans__‐diphenyl‐substituted (**8b**, **8c*
