compounds for the synthesis of many biologically active compounds, efficiently under 1 atm of CO2. The readily available nature of the different starting materials and tolerance of variousfunctionalgroups provide vast opportunities for the efficient construction of diversified libraries for bioactive compounds listed in Figure 1. As an example, this methodology has been applied to the synthesis of Lotronex

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
