the chiral eluant hplc procedure is easily scaled up for the semipreparative resolution of several ornithine analogs , i.e. , alpha-fluoromethylornithine , alpha-difluoromethylornithine , alpha-chlorofluoromethylornithine , and alpha-fluoromethyldehydroornithine , which are known as potent ornithine decarboxylase inhibitors in vitro and in vivo .
