A highly regioselective synthesis of novel dispiroheterocycles by the cycloaddition of azomethine ylide generated through a decarboxylative route from sarcosine/proline/thiazolidine-4-carboxylic acid/1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid and ninhydrin with the dipolarophile 3-arylidene-4-chromanone is described.
