PIDA-promoted metal-free [3 + 2] heteroannulation of β-ketothioamides with 4-hydroxy coumarins: chemo-/regioselective access to furo[3,2-]chromen-4-ones at room temperature

Herein, we report a viable protocol to access furo[3,2- c ]chromen-4-ones by engaging easily accessible 4-hydroxy coumarins as a three-atom CCO unit and thioamides as a C2 coupling partner, mediated by phenyliodine( iii ) diacetate (PIDA) at room temperature in a highly efficient and pot-/step-econo...
