Carrying out the reaction with aliphatic amines or aminoalcohols at a higher temperature (80 degrees C), phosphinoyl-functionalized 3-aminomethylene chromanones were formed instead of the corresponding chromonyl-substituted alpha-aminophosphine oxides. No reaction occurred when 3-formyl-6-methylchromone and secondary phosphine oxides were reacted with aromatic amines in the absence of any catalyst. Applying a basic catalyst, the formation of the phosphinoyl-functionalized 3-aminomethylene chromanones was observed; however, the reaction was not complete. Detailed experimental and quantum chemical studies were performed to study the transformation. Moreover, the in vitro cytotoxicity of phosphinoyl-functionalized 3-aminomethylene chromanones was also investigated in three different cell lines, such as human lung adenocarcinoma (A549), mouse fibroblast (NIH/3T3), and human promyelocytic leukemia (HL60) cells.
