An environmentally benign cascade redox-neutral process was developed for the efficient construction of pharmaceutically significant spirocyclic tetrahydro-quinolines via a 3-step cascade Knoevenagel condensation/[1,5]-hydride transfer/cyclization, which features green and additive-free conditions, wide substrate scope, and high step- and atom-economy.

A new method was developed for the one-stepsynthesis of spiro derivatives of fused quinolines by the reactions of ortho-amino derivatives of benzaldehyde with Meldrum"s acid, cyclohexane-1,3-dione, or N,N"-disubstituted barbituric acids.
