Diversified assembly of perfluoroalkyl-substituted furans and 2,5-dihydrofuran-2-ols
摘要:
We have developed a facile and effective synthesis of 3-iodofurans from 3-monosubstituted 1,2-allenyl perfluoroalkyl ketones or 2-hydroxy-4-iodo-2,5-dihydrofurans from 3,3-disubstituted 1,2-allenyl perfluoroalkyl ketones. The perfluoroalkyl substituent and the amount of water in the solvent are important for the success of this electrophilic cyclization. (C) 2010 Elsevier Ltd. All rights reserved.
