Abstract

Evidence supporting an enzyme-catalyzed [3,3]-sigmatropic rearrangement of the dimethallylltryptophan synthase is highlighted. A bioinspired system is discussed, by which the chemical feasibility of Cope rearrangement to the 4-position of the indole nucleus was accomplished. Furthermore, synthesis of the tricyclic benzo[cd]indole core of welwitindolinones and dragmacidine E is presented.
