Synthesis of α,α-diarylacetamides from benzyl aryl ketones using 2-azido-1,3-dimethylimidazolinium hexafluorophosphate
摘要:
Benzyl aryl ketones reacted with 2-azido-1,3-dimethylimidazolinium hexafluorophosphate (ADMP, 1) to give migratory amidated compounds, which were transformed into the corresponding diarylacetamides by treating with LiAlH(4). (C) 2011 Elsevier Ltd. All rights reserved.
α-Arylcarboxylic acid amides were synthesized by reacting silyl enol ethers of aryl ketones and 2-azido-1,3-dimethylimidazolinium hexafluorophosphate (ADMP, 1). Silyl enol ethers react with ADMP 1 to give N-(α-arylacyl)guanidines via the migration of aryl groups in enol ethers. The products were transformed to the corresponding α-aryl acetamides by treating with LiAlH4.
