Direct α-Arylation of α-Amino Carbonyl Compounds with Indoles Using Visible Light Photoredox Catalysis
摘要:
A general and mild method for the construction of functionalized 2-(1H-indol-3-yl)-2-amino-carbonyl compounds was achieved, which represents the first example of direct alpha-arylation of alpha-amino carbonyl compounds with indoles using the visible light photoredox catalysis strategy.
Regiodivergent Synthesis of Penta-Substituted Pyrroles through a Cascade [3 + 2] Cyclization of C-Acylimines with Activated Alkynes and Aromatic Nucleophiles
one-pot, four-component cascade cyclization reaction of α-keto aldehydes, anilines, activatedalkynes, and aromatic nucleophiles is developed to synthesize a diverse range of pharmaceutically important penta-substituted pyrroles. The reaction proceeds through the cascade cyclization of acylimines (in situ formed) with activatedalkynes and aromatic nucleophiles such as indoles, pyrroles, and naphthols at
