An one-pot efficient diastereoselective 1,3-dipolar cycloaddition of diethyl 2-aminomalonate, benzaldehydes and 3-nitro-2H-chromenes has been developed. Catalyst-free conditions, facile procedure and high yields of the polysubstituted benzopyrano[3,4-c]-pyrrolidines are the salient features of this methodology.
