Abstract: An unexpected FeCl3-promoted reaction of cyclic imine dibenzo[b,f][1,4]oxazepines with alkynes was studied, leading to a series of 4-substituted 3-(2-hydroxyphenyl)-quinolines. A variety of substituted cyclic imines and terminal alkynes (arylacetylenes, conjugated enynes, and 1,3-diynes) were used… read more here.
