We
contributed a new benzimidate chemistry through moisture-insensitive
NiII/NiII-FeIII combo-catalysis for
a simultaneous 2–3 bond-forming gem-diamidation
and amidoindolyzation cascade reaction to construct symmetrical and
unsymmetrical gem-(arylmethylene)amides and indolo(arylmethylene)amides,
using emerging benzimidate synthons. The operational simplicity, mild
nature, generality, and robustness of the strategy were validated
through syntheses of a wide range of new molecules, labile sugar-based
chiral compounds, and pharmaceuticals with high yields under the same
reaction conditions.
