Article abstract of DOI:10.1007/BF00473488

The splitting of the dihydropyridine ring of N-methyl-substituted 4-phenyl-5-oxo-4,5-dihydroindeno<1,2-b>pyridine in an acid medium takes place at the C-N bond.During the splitting of 1,2-dimethyl-4-phenyl-4,5-dihydroindeno<1,2-b>pyridine, 4-phenyl-4-(ind
