Chalcone Aziridines. III. Reaction of trans-Chalcone Aziridines with Isocyanates, Isothiocyanates and HSCN The reaction of 2-aryl-3-aroyl-aziridines 1 with phenyl isocyanate or mustard oils leads to N-phenylcarbamoyl derivatives 2a–2q and 2-amino-thiazolines 6 a, h, n, r , respectively. From 2 m and NaI the imidazolin-2-one 3 was obtained. By treatment of 2 with HSCN the regiosomeres 2(3)-ureido-3(2)-rhodano-1. 3-diaryl-propan-1-ones 4 a, h, m and 5 f were formed.
