Abstract: Indole dearomatization of tryptophan represents a key approach in the synthesis of indole containing alkaloids. Although the reactivity of C-3a-bromo-, 3a-iodo-, and 3a-chloropyrroloindolines has been explored, the utility and reactivity of C-3a-fluoropyrroloindolines has remained untapped.… read more here.
