monoaddition using the sterically hindered 2-isoprenylindole. This permits addition of the second indole, 7-prenylindole, which gives both meta- and para-substituted bis-indolylquinone products. This regiochemical control problem was solved by extension of a method we recently developed for acid-promotedaddition of indoles to 2,5-dichlorobenzoquinone. Under our original mineral acid conditions, reaction
