Direct Construction of 2‑Aryliminochromenes from Arynes, <i>N</i>,<i>S</i>‑Keteneacetals, and DMF
A concise and direct
synthetic strategy for the construction of
2-aryliminochromene skeleton by cascade three-component coupling reaction
of arynes, <i>N</i>,<i>S</i>-keteneacetals, and
DMF in good yields has been disclosed. The process demonstrates the
first example of aryne chemistry combined with <i>N</i>,<i>S</i>-keteneacetals. Using this strategy, an expeditious synthesis
of biologically important arylimino-2<i>H</i>-chromene-3-
carboxamides was achieved
