✦ Synopsis
Cyclols as Intermediates in the Reaction of 3‐(Dimethylamino)‐2,2‐dimethyl‐2__H__‐azirine with Monosubstituted Parabanic Acids; a New and Unexpected Rearrangement
The reaction of 3‐(dimethylamino)‐2,2‐dimethyl‐2__H__‐azirine (1) with N‐methylparabanic acid (4) in 2‐propanol at room temperature gives the cyclol 5 in 97% yield. In acetonitrile solution 5 rearranges to the imidazoline derivative 6 (Scheme 2). The structures of the unexpected products 5 and 6 have been established by X‐ray crystallography.
