Unexpected reaction of 2-hydrazinoperimidine with maleic anhydride: Syntheses of (8-amino-9-oxo-9,10-dihydro-8H-imidazo[1,2-a]perimidin-10-yl)acetic acid and its azomethine derivatives. Heterocycles 68 (4) : 821-828. ScholarBank@NUS Repository. https://doi.org/10.3987/COM-06-10678 | Abstract: | The reaction of 2-hydrazinoperimidine (3) and maleic anhydride in mild conditions afforded the formation of an unexpected product, namely (8-amino-9-oxo-9,10-dihydro-8H-imidazo[1,2-a]perimidin-10-yl)acetic acid (5). The possible mechanism of this reaction is discussed. Schiff bases (9a-f) were prepared from 5 using corresponding aldehydes. The structures of the prepared compounds were established with spectral analysis including NOESY 2D experiments.{A figure is presented}. © 2006 The Japan Institute of Heterocyclic Chemistry. | Source Title: | Heterocycles | URI: | http://scholarbank.nus.edu.sg/handle/10635/106483 | ISSN: | 03855414 | DOI: | 10.3987/COM-06-10678 |
