Copper-catalyzed cyclization of an oxime ester toward divergent heterocycle synthesis is reported. Oxime ester serves as an enamine precursor to cyclize with malononitrile and aldehydes for access to 2-aminonicotinonitriles in a one-pot reaction, while cyclizing with N-sulfonylimines leads to synthesis of pyrazolines.

Abstract 2-Amino-3-cyanopyridine derivatives were synthesized in an ultrasonic bath and one pot four-component reactions with high yields, in a short time, without solvent and catalyst, and anticancer activity studies on MCF7, DU145, and HepG2 cell lines were investigated. 18 compounds were synthesized in 4–25 min time interval and 85–99% yield. Among these compounds, the IC50 values in 7a, 6a, and
