Abstract

2008Furan derivatives R 0060 Expedient Syntheses of β-Iodofurans by 5-endo-dig Cyclizations. -A general approach to the title compounds is developed using I 2 as the electrophile. The iodine substituent allows further functionalization to give highly substituted furan systems.Substrates bearing a terminal alkyne moiety [cf. (Vc)] do not react. -(BEW, S. P.; EL-TAEB, G. M.
