The invention relates to a process for preparation of radiopharmaceutical precursors, and in particular protected amino acid derivatives which are used as precursors for production of radiolabeled amino acids for use in in vivo imaging procedures such as positron emission tomography (PET). Particularly, the invention relates to a process for preparation of a precursor of the [18F]-1-amino-3- fluorocyclobutanecarboxylic acid ([18F] FACBC) PET agent and particularly to the work-up process of this precursor removing generated salts from the intermediate composition.
PROCESS FOR PRODUCTION OF PRECURSOR COMPOUND FOR RADIOACTIVE HALOGEN-LABELED ORGANIC COMPOUND
-
Page/Page column title page; 7-8; 11, (2009/12/23)
A process for producing a labeled precursor which is useful for production of a radioactive fluorine-labeled amino acid compound is provided. In the reaction step for introducing a leaving group to a mixture of syn-form and anti-form of FACBC, a base is a
Diastereoselective synthesis of hydantoin- and isoxazoline-substituted dispirocyclobutanoids
Park, Kyung-Ho,Kurth, Mark J.
, p. 3520 - 3524 (2007/10/03)
Synthetic strategies for constructing novel achiral cyclobutanoid isoxazolidinoimidazolidinedione heterocycles, with a generalized structure of II, have been developed via 1,3-dipolar cycloaddition and carbanilide cyclization transformations from methylenecyclobutane 13. The exo methylene cyclobutane system has made the realization of some diasteroselectivity possible, such that the H-bond (Boc-NH) directed product (i.e., 14) was obtained with 3:1 selectivity relative to the non-H-bond directed product (i.e., 15).
