Abstract

A general method is reported for the parallel solid-phase synthesis of hydroxypiperazine derivatives based on the oxidation–Cope elimination of polymer-bound phenethylamine linker with m-CPBA. The key intermediate of phenethylamine N-oxide resins was separable on solid-phase for subsequent β-elimination, from which the desired hydroxypiperazine products could be obtained in high purities and yields without any significant ...
