Selenium dioxide-mediated methoxyhydroxylation of cyclic arylolefin
摘要:
Selenium dioxide-mediated methoxyhydroxylation of cyclic arylolefin with the modest yields is described. This facile strategy was also used to synthesize several 4-arylpyridines, 3-hydroxy-4-arylpyridines, and 3,4-diarylpyridines. Crown Copyright (C) 2010 Published by Elsevier Ltd. All rights reserved.

Fe(OTf)3-catalyzed synthesis of acyclic β-aminoketones from 3-aryl propargyl alcohols and nitrogen nucleophiles were investigated. Results showed that propargyl alcohols without bulky groups α to the hydroxyl group underwent the transformation smoothly. Sulphonamides exhibited the higher reactivity than amides as the nitrogen nucleophiles and the transformation of acyclic β-aminoketones were finished
