Cover Feature: Experimental and Theoretical Studies on the Reactions of Aliphatic Imines with Isocyanates (Chem. Eur. J. 14/2024)

Only products resulting from [4+2] cycloaddition pathways were observed in the reactions of different isocyanates with aliphatic imines. The alternative [2+2] pathway is strongly disfavored, and the corresponding diazetidinone products were not observed. For imines incorporating a specifically located thioester group, acyl isocyanates and aryl isocyanates gave different final products. More information can be found in the Research Article by K.-H. Altmann and co-workers (DOI: 10.1002/chem.202304272).
