  1. Abstract

    We describe herein formal syntheses of the indole alkaloidscis‐trikentrin A and herbindole B from a commonmeso‐hydroquinone intermediate prepared by a ruthenium‐catalyzed [2+2+1+1] cycloaddition that has not been used previously in natural product synthesis. Key steps include a sterically demanding Buchwald–Hartwig amination as well as a unique C(sp3)−H amination/indole formation. Studies toward a selective desymmetrization of themeso‐hydroquinone are also reported.
