Facile access to indolo[2,3- <i>b</i> ]quinoline alkaloids <i>via</i> DMSO-mediated cascade cyclization: unveiling their photophysical potential

A concise method for Indolo[2,3- b ]quinoline synthesis via C3-alkylated indoles with DMSO/HCl delivers direct annulation, broad scope, high yield, scalability, and tunable blue–green fluorescence from excited-state proton transfer.
