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.

DOI: 10.1039/d4ra05619a
Abstract: A caesium carbonate-promoted reaction of nitro-substituted donor–acceptor cyclopropanes (DACs) with primary aromatic amines in water provides a convenient access to β-enamino malonates under mild reaction conditions. The transformation takes place through the formation of allene… read more here.
