REDUCTION AND ALKALINE HYDROLYSIS OF 5-OXOINDENOPYRIDINIUM SALTS

Article abstract of DOI:10.1007/BF00475479

5,9b-Dihydro derivatives of indeno<1,2-b>pyridine were obtained by the reduction of the corresponding 1,2-dimethyl-4-aryl-5-oxoindeno<1,2-b>pyridinium perchlorates. 1,2-Dimethyl-3-ethoxycarbonyl-4-phenyl-5-oxoindeno<1,2-b>pyridinium perchlorate forms in alkaline medium with splitting, recyclization and deamination products.
