Rh( <scp>ii</scp> )-catalyzed synthesis of furo[2,3- <i>b</i> ]indoles from 3-diazooxindoles and electron-rich arylacetylenes
We report a Rh(II)-catalyzed synthesis of aromatic furo[2,3-<i>b</i>]indoles <i>via</i> cyclopropenation of 3-diazooxindoles with arylacetylenes, followed by <i>in situ</i> rearrangement. A unique aspect of this transformation is the unprecedented activation of the otherwise inert C-2 oxygen atom of the diazooxindole moiety, providing a mild and efficient route to pharmaceutically relevant furoindole scaffolds.
