Research Abstract |
A concise method for the synthesis of heterocycle-fused naphthoquinones such as 1H-benz[f]indole-4,9-dione was developed. This method employed Sonogashira coupling and tandem addition-elimination/intramolecular cyclization, and it enabled the preparation of versatile heterocycle-fused naphthoquinones from one substrate. However, introduction of C1 unit at 3-position was failed. Alternatively, we developed direct methods for the synthesis of 3-substituted indoles from o-alkynylanilines by utilizing a copper-catalyzed tandem intramolecular cyclization/coupling reaction. Moreover, we developed an efficient method for the transformation of indoles by utilizing a copper catalyst and molecular oxygen as the oxidant. The transformation involves a tandem oxidative process of 2-arylindoles. Our reaction afforded a variety of N-benzoyl anthranilic acids and benzoxazinones.
