ChemInform Abstract: A Catalyst-Free, One-Pot Multicomponent Synthesis of Spiro-Benzimidazoquinazolinones via a Knoevenagel-Michael-Imine Pathway: A Microwave Assisted Approach.
A facile, swift and ecofriendly microwave-assisted multi-component/one-pot protocol is designed for the synthesis of novel pyrazolo-[3,4-b]-quinolines at ambient temperature in aqueous ethanol as a reaction medium.
