An effective method for the synthesis of aryl hydrazines by amination of anilines using the solid-supported phenylsulfonyl-hydroxylamine was described. Treatment of aniline with the solid-supported aminating agent, followed by removal of the resin, provided the corresponding hydrazine in 21% yield. The resulting hydrazines were directly adapted to the solid-phase synthesis of indoles, providing nine
[reaction: see text] We describe a new approach for the solid-phase synthesis of indoles 1 that involves a one-pot release and cyclization reaction of a solid-supported hydrazone through a Wang-type linker. Using this solid-phase methodology, we accomplished the synthesis of 40 naltrindole derivatives.
