An efficient, novel metal-catalyst-free aminobenzannulation of 2-(prop-2-ynyl)(oxo)benzenes 1 with various dialkylamines 2 afforded a variety of 2-aminonaphthalenes 3 in good to excellent yields under mild reaction conditions at room temperature to 100 degrees C (at most).
One-Pot Synthesis of Highly Substituted Aromatic Amine Derivatives via Pd-Catalyzed Aminobenzannulation Reaction
convenient Pd(0)-catalyzed carboannulation with propargylic compounds for the synthesis of highlysubstituted aromatic amine derivatives in a one-pot operation was developed. In this process, a significant breakthrough in aminobenzannulation is observed. Moreover, the reaction appears to be very general and suitable for a variety of amines.
