| Outline of Final Research Achievements |
Oxidative 1,2-difunctinalization of alkene with hypervalent iodine reagent offers a powerful strategy for constructing diverse molecular complexity, because a wide range of functional groups, such as oxygen, nitrogen, halogen, and sulfur nucleophiles, is incorporated into the C=C of alkene substrates. Compared to the most often reported carbon-heteroatom bond forming processes, the scope of oxidative carbon-carbon bond formation is still limited.
We found that enantioselective oxyarylation of (E)-6-aryl-1-silyloxyhex-3-ene and aminoarylation of N-sulfonyl-6-phenylhex-3-en-1-amine proceeded with high enantioselectivity. The silyloxy group does not act as a protection group, however, it preferentially promotes the nucleophilic oxycyclization. The aminoarylation provides hexahydrobenz[e]indoles, which are candidates of an agonist/antagonist for dopamine and serotonin receptors.
