An one-pot stereoselective synthesis of 2-aminobenzylidene derivatives from readily available 5-nitro/cyano-activated 2-halobenzaldehydes (2-chloro-5-nitrobenzaldehyde, 2-bromo-5-nitrobenzaldehyde, 2-fluoro-5-nitrobenzaldehyde, 5-cyano-2-fluorobenzaldehyde), the active methylidene compounds (cyanoacetamide and ethyl cyanoacetate), and secondary cycloamines via a novel parallel convergent Knoevenagel–nucleophilic
