A Facile Synthesis of 4,4-Bis(trifluoromethyl)imidazolines via a Novel Oxidative Imidazole Rearrangement
摘要:
Oxidation of imidazole (1) with singlet oxygen or m-chloroperbenzoic acid affords novel 4,4-bis(trifluoromethyl)imidazolines in high yield via a unique oxidative ring opening and subsequent acid catalyzed dehydrocyclization.
