An unprecedented PTSA-promoted furan annulation and aromatization in one pot has been developed. This process offers a simple and efficient synthetic route for the construction of various highly substituted benzo[b]furan derivatives, which are widely used not only in drug active molecules but also organic semiconductor and organic light-emitting devices. The preliminary mechanism study indicated this transformation proceeded sequentially via furan annulation and aromatization.
Rhodium(III)-catalyzed redox-neutral coupling of N-phenoxyacetamides and alkynes with tunable selectivity

Give it a tweak: A novel oxidizing directing group was developed for a rhodium(III)-catalyzed C-H functionalization of N-phenoxyacetamides with alkynes. A small change in the reaction conditions leads to either ortho-hydroxyphenyl-substituted enamides or cyclization to deliver benzofurans with high selectivity (see scheme; Cp=C5Me5). Copyright
