General description
Versatile indole-based linker for the synthesis of secondary amides, carbamates, ureas [1,2,3,4] and aminopurines [5]. In a study comparing the cleavage rates of secondary amides, ureas, carbamates and sulfonamides from indole, dialkoxybenzaldehyde and Rink amide resins, the indole resin was found to be the most acid-labile [6].Reductive amination with excess of amine and NaBH(OAc)3 in DCE/TMOF [seepage], NaBH3CN in THF/TMOF/AcOH, or NaBH4-Ti(OiPr)4 in THF [2], converts the formyl group to the appropriate secondary amine. Cleavage can be effected with 2-5% TFA in DCM, depending on the nature of the product being released from the resin.
