    摘要: A method of preparing a tetrabenazine compound (TBZ compound) having structure I comprising the steps of reacting a nucleophilic alkenyl species with aldehyde compound II and oxidizing the resultant allylic alcohol to provide enone III. The protecting group P1 on the tetrahydroisoquinoline nitrogen is removed and the resultant deprotected intermediate is induced to undergo an amino cyclization reaction to provide a product TBZ compound having structure I. The method may be used to prepare either enantiomeric form of tetrabenazine; (+)-tetrabenazine or (−)-tetrabenazine. Alternatively the method may be adapted to provide a mixture enriched in one tetrabenazine enantiomer, a racemic mixture, or a diastereomeric mixture of tetrabenazine compounds. In addition, the present invention provides novel synthetic intermediate compositions which may be used to prepare either or both enantiomers of tetrabenazine, derivatives of tetrabenazine, and analogs of tetrabenazine.

    摘要: The present invention provides novel fluorophilic compounds having structure VII wherein R1 is a C1-C20 aliphatic, a C2-C20 cycloaliphatic, or a C2-C20 aromatic radical comprising at least one functional group susceptible to reaction with nucleophilic fluoride ion or an electrophilic fluorinating agent; R2 is a C1-C10 aliphatic radical; R3 is hydrogen or a C1-C10 aliphatic radical; R4 is hydrogen or a C1-C10 aliphatic radical; and R5 is hydrogen, a C1-C10 aliphatic radical, a C2-C10 cycloaliphatic radical, or a C2-C20 aromatic radical. The fluorophilic compounds are provided in both racemic and enantiomerically enriched forms and are useful as intermediates in the preparation of novel PET imaging agents and probes useful in the discovery and performance assessment of PET imaging agents. The fluorophilic compounds are particularly useful in the preparation of PET imaging agents and probes having a high affinity for VMAT-2, a biomarker implicated in human diabetes and other illnesses such as Parkinson's disease.

    摘要: The present invention provides novel fluorinated ether compounds having structure I wherein R1 is a C2-C10 fluorinated aliphatic radical; R2 is a C1-C10 aliphatic radical, or a C3-C10 cycloaliphatic radical; R3 is hydrogen or a C1-C10 aliphatic radical; and R4 is hydrogen or a C1-C10 aliphatic radical. The fluorinated ether compounds are provided in both racemic and enantiomerically enriched forms and may comprise either or both of fluorine-18 and fluorine 19. The fluorinated ether compounds are shown to possess high affinity for VMAT-2, a biomarker implicated in human diabetes. The fluorinated ether compounds comprising a fluorine-18 group are useful as PET imaging agents targeting the VMAT-2 biomarker. The non-radiolabeled fluorinated ether compounds are useful as probes for the discovery of PET imaging agents.
