Abstract

Alkylation of 3-methoxycarbonyl-2-methyl-5-oxo-4,5-dihydro-1H-indeno[1,2-b]pyridine and 12-oxo-12,13-dihydro-7H-7azaindeno[1,2-b]phenanthrene using methyl iodide or allyl bromide in DMF solution in the presence of NaH occurs with high selectivity and gives the corresponding C-alkyl derivatives in high yield. The acid cleavage of the 4a-alkylated 3-methoxycarbonyl-2-methyl-5-oxo-4a,5-dihydroindeno[1,2-b]pyridines has been studied.
