Abstract

Piperazino-and piperidino-functionalized polystyrenes have been examined as deblocking- scavenging agents for the 9-fluorenylmethyloxycarbonyl (Fmoc) amino-protecting group. Both commercial and synthesized polystyrenes have been used as supports. In order to introduce the active functional groups,(chloromethy1)-polystyrene 2 was treated with tert- butyl piperazine-1-carboxylate followed by acidic deblocking (HCl/dioxane) or, ...
