Synthesis of Enantiopure Piperazines via Asymmetric Lithiation-Trapping of N-Boc Piperazines: Unexpected Role of the Electrophile and Distal N-Substituent
A new method for the synthesis of enantiopure α-substituted piperazines via direct functionalization of the intact piperazine ring is described. The approach utilizes the asymmetric lithiation-substitution of an α-methylbenzyl-functionalized N-Boc piperaz

Use of polymer supported reagents for clean multi-step organic synthesis: Preparation of amines and amine derivatives from alcohols for use in compound library generation
The automated sequential application of polymer supported perruthenate (PSP) and polymer supported cyanoborohydride (PSCBH) in an oxidation-reductive amination procedure allowed the efficient transformation of simple alcohols into more complex amines which can be further derivatised by the use of polymer bound amino sulfonylpyridinium chlorides.
