hydrocarboxylation of 2‐alkynylanilines under very mild conditions has been developed to afford (E)‐[2‐(o‐aminophenyl)]acrylic acids, which could easily be converted to (E)‐3‐alkylidene‐2‐indolinones with important potential bioactivity. The stereoselective syntheses of two biologically active molecules, (E)‐3‐benzylidene‐2‐indolinone (chemo‐preventive potential in inducing NQO1 activity) and (E)‐3‐(3‐m
