The reaction between enamines and azaenamines containing a thioamide group and dimethyl acetylenedicarboxylate was studied under various conditions. It was shown that exchanging one of the carbon atoms in the structure of the investigated compounds for a nitrogen atom significantly affected the reactivity. Functionalized thiopyrans and thiazolidinones were obtained during this investigation.

The synthesis and in vitro cytotoxic characteristics of new imidazo[1,2‐b]pyrazole‐7‐carboxamides were investigated. Following a hit‐to‐lead optimization exploiting 2D and 3D cultures of MCF‐7 human breast, 4T1 mammary gland, and HL‐60 human promyelocytic leukemia cancer cell lines, a 67‐membered library was constructed and the structure–activity relationship (SAR) was determined. Seven synthesized
