An efficient furan synthesis using heterogeneous catalysis
摘要:
A wide variety of 3-alkyne-1,2-diols have been found to undergo exceptionally clean 5-endo-dig cyclisations followed by dehydration at ambient temperature to give the corresponding furans in essentially quantitative yields when exposed to 10 mol % of 10%,w/w silver(1) nitrate absorbed on silica gel.
