Synthesis of benzo[c]-2,7-naphthyridines by palladium-catalyzed coupling of pyridine methylstannanes with ortho bromoacetanilides in the presence of copper(II)oxide
benzo[c]-2,7-naphthyridine have been prepared in fair to excellent yields and in one step by the Pd(0)-catalyzed cross-coupling of pyridine methylstannanes with ortho bromoacetanilides. The coupling is greatly promoted by the addition of copper(II)oxide.
Electro‐oxidative Methylation of 2‐Isocyanobiaryls Using <i>N</i>,<i>N</i>‐dimethylformamide (DMF) as Carbon Source: Synthesis of 6‐Methylphenanthridines
This study reported the synthesis of 6-methylphenanthridines from 2-isocyanobiaryls using dimethylformamide (DMF) as a methyl carbon souce. The reactions were conducted in open-air atmosphere using electrochemical process at ambient temperature.
