Co?kun, Necdet,?etin, Meliha
experimental part, p. 2053 - 2060 (2010/04/26)
Isoxazolines 2 from the cycloaddition of imidazoline 3-oxides 1 with DMAD undergo rearrangement to 3,4-dihydro-2H-imidazol-1-ium-1-(1,2-bis-methoxycarbonyl-2-oxo-ethanides) 3, which spontaneously undergo elimination to give 3H-imidazol-1-ium-1-(1,2-bis-me

experimental part, p. 648 - 658 (2009/04/07)
Isoxazolines 2 from the cycloaddition of imidazoline 3-oxides 1 with DMAD rearrange in the presence of methoxide to give cis-3-methoxy-7-(methoxycarbonyl)-2,7a-diaryl-5-oxo-2,3,5,7a-tetrahydro-1H-pyrrolo[1,2-e]imidazol-6-olates 3 with 100% de. The acidic
Synthesis of di- and cis-triaryl-3a,4,5,6-tetrahydroimidazo[1,5-b]isoxazoles and their ring-opening reactions
