A new method for the synthesis of naphthostyrils is described. In this method, a sequential Stille coupling and proline-catalyzedcyclization procedure is employed for the reaction of 4-bromooxindoles and β-tributylstannyl-α,β-unsaturated ketones. The utility of this methodology is demonstrated in the first totalsynthesis of prioline from a simple 2-isopropylphenol.
