Research Abstract

Borderline metal-catalyzed cycloisomerization of amino-allenes were investigated. In the reaction, we found that bismuth(III) triflate were more effective catalyst to proceed the reaction than other transition metal catalysts. The bismuth-catalyzed hydroamination can be applied to tandem ene-hydroamination of amino-allenes and amino-olefins with activated olefins and benzyl alcohols to provide multi-substituted N-heterocycles in good yields. In addition, we developed a cationic iron-catalyzed intramolecular hydroarylation of alkynes. In this reaction, the cationic iron catalyst promoted the addition of electron deficient arenes possessing strong electron-withdrawing group to alkynes, efficiently. This reactivity was very unique in comparison with other traditional catalysts for the similar hydroamination.
