摘要

An efficient synthetic route to prepare two new HYNIC derivatives with a 2-nitroimidazole moiety designed for tumor hypoxia imaging is described. During the course of the synthesis, the optimization of N-alkylation reaction of 2-nitroimidazole with propargyl bromide is reported to favor the formation of the terminal alkyne versus allene. Thereafter, the two ligands were used with tricine/EDDA to complex99MTc. However, decomposition of these ...
