One‐pot three‐component reaction for indole‐spiro (indene‐pyrrolidine) highly strained molecules were synthesized with moderate yield by 1,3‐cycloaddition of unsymmetrical dipolarophiles, prepared from indol‐3‐yl and 1‐acetyl‐1H‐indol‐3‐yl derivative with azomethineylide generated through decarboxylative addition of amino acid sarcosine and ninhydrine, which is confirmed by NOESY. Our method is to
