A Synthetic Route to Highly Substituted 1‑Aminonaphthalenes from Readily Available Benzaldehydes

open access: yes
We report an efficient route for the synthesis of highly substituted 1-aminonaphthalenes from benzaldehydes. The method employs a stereoselective Still–Gennari modification of the Horner–Wadsworth–Emmons olefination to afford (E)-benzylidene ...

Iridium-Catalyzed Direct ortho-C–H Amidation of Benzaldehydes through N‑Sulfonyl Imines as Mask

open access: yes, 2016
Ir-catalyzed direct C–H sulfamidation of benzaldehydes has been achieved. A series of ortho-amided benzaldehydes were obtained in up to 95% yields for 21 examples with excellent regioselectivity and broad functional group tolerance.
