Chalcone Aziridines. III. Reaction of trans-Chalcone Aziridines with Isocyanates, Isothiocyanates and HSCN

Weber, Fritz Gerd,Liepert, Harald,Koeppel, Hubert

, p. 612 - 620 (2007/10/02)

The reaction of 2-aryl-3-aroyl-aziridines 1 with phenyl isocyanate or mustard oils leads to N-phenylcarbamoyl derivatives 2a-q and 2-amino-thiazolines 6a, h, n, r, respectively.From 2m and NaI the imidazolin-2-one 3 was obtained.By treatment of 2 with HSCN the regioisomers 2(3)-ureido-3(2)-rhodano-1.3-diaryl-propan-1-ones 4a, h, m, and 5f were formed.
