| tert-Butyl 1-piperazinecarboxylate Usage And Synthesis |
| Uses | N-Boc-piperazine is a compound useful in organic synthesis. | | Chemical Properties | Waxy Solid | | Uses | 1-Boc-piperazine undergoes Buchwald-Hartwig amination with various aryl halides to form corresponding amine derivatives. It can be used to synthesize monosubstituted piperazine intermediates of many bioactive molecules and piperazine containing drug substances, such as trazodone. | | Uses | 1-Boc-piperazine may be used in:- preparation of series of (m-phenoxy)phenyl substituted piperazine derivatives
- termination step during synthesis of α,β-poly(2-oxazoline) lipopolymers via living cationic ring opening polymerization
- preparation of monosubstituted piperazines, e.g. in the synthesis of indazole DNA gyrase inhibitors
| | General Description | 1-Boc-piperazine is an N-Boc protected piperazine. Crosscoupling of 1-Boc-piperazine with aryl iodides using CuBr/1,1′-bi-2-naphthol (catalyst) and K3PO4 (base) has been reported. 1-Boc-piperazine undergoes Buchwald-Hartwig coupling reactions with aryl halides. 1-Boc-piperazine can be prepared in 80% yield via solvent-free N-Boc protection catalyzed by iodine. |
