Abstract

1,5-Disubstituted indole-2-carboxaldehyde derivatives (1ah) and glycine alkyl esters (2ac) are shown to undergo a novel cascade imination-heterocylisation in the presence of organic base DIPEA to provide 1-indolyl 3,5,8-substituted g-carbolines (3aaea) in good yields. The g-carbolines are fluorescent and exhibit anticancer activities against cervical, lung, breast, skin and kidney cancers.

Keywords: γ-Carboline; cascade reaction; cytotoxicity; cell uptake; density functional theory; fluorescence.
