SmI2-mediated facile one-pot preparation of 2,4-diarylquinolines from 3-aryl-2,1-benzisoxazoles
摘要:
Oil treatment with SmI2, 3-aryl-2, 1-benzisoxazoles undergo reductive cleavage of the N-O bond leading to 2-aminobenzophenones in high yields upon protonation. If aryl methyl ketones are added to the reaction mixture prior to protonation, the desired 2,4-diarylquinolines can be obtained in moderate yields under mild conditions.

A rhodium(III)‐catalyzed C−H amination of benzamides and isoquinolones with anthranils has been realized under assistance of weakly coordinating amide, leading to a bifunctionalized amination product which can further cyclize to acridine under in situ or ex situ conditions.
