A unique alkene difunctionalization reaction that allows rapid construction of molecular complexity around the biologically relevant indole framework has been developed. The reaction proceeds with up to 87% yield, 99:1 er, and >20:1 dr. Evaluation of several of the compounds revealed promising anticancer activity against MCF-7 cells.

Hypervalent iodine mediated alkene difunctionalization of vinylphenols: diastereoselective synthesis of substituted indoles and indolizines
A hypervalent iodine mediated alkenedifunctionalization reaction of vinylphenols has been developed. The chemistry is applicable to a wide range of substitutions on both the alkene and nucleophile substrates, enabling the rapid synthesis of 3-substituted indoles and 2-substituted indolizines in good yields and high diastereoselectivities under metal-free conditions.
