Ni-Catalyzed Direct Reductive Amidation via C–O Bond Cleavage
摘要:
A novel Ni-catalyzed reductive amidation of C(sp(2))-O and C(sp(3))-O electrophiles with isocyanates is described. This umpolung reaction allows for an unconventional preparation of benzamides using simple starting materials and easy-to-handle Ni catalysts.

A palladium-catalyzed [3 + 2] annulation of substituted aromatic amides with maleimides providing tricyclic heterocyclic molecules in good to moderate yields through weak carbonyl chelation is reported. The reaction proceeds via a dual C–H bond activation where the first C–Hactivation takes place selectively at the benzylic position followed by a second C–H bond activation at the meta position to
