Facile solid-phase construction of indole derivatives based on a traceless, activating sulfonyl linker

Abstract

[reaction: see text] Palladium-mediated coupling/intramolecular indole cyclization of terminal alkynes with resin 8, followed by cleavage of the sulfonamide linkage, were executed under mild conditions to provide diverse indoles 10 in excellent yield and purity. This chemistry benefits from a dual-activation process that derives from use of a traceless N… (More)
