Description: RAM and PAL are commercially available and require relatively high concentrations of TFA for complete cleavage. Reductive amination of aldehydes and ketones using sodium cyanoborohydride and Rink’s 4-(2′,4′-dimethoxyphenyl-aminomethyl)-phenoxymethyl-linked polystyrene resin [Rink’s amine linker on copoly-(styrene-1%-divinylbenzene)] affords high yields of linker-bound, N-alkyl amines with excellent chemical selectivity. Subsequent coupling with acid derivatives gave derivatized N-substituted amides in excellent yields after cleavage from the solid-support. The synthesis of N-alkyl amides was more difficult on a Rink amide resin, especially the coupling of the first amino acid to the N-alkyl amine, resulting in lower yields for loading the first amino acid onto the resin.
