Sequential Radiosynthetic Methodology: Assembly of Boronic Ester Precursors on a Diol Resin and Radioiodination Using Copper-Mediated Radioiododeboronation and Azide-Alkyne Cycloaddition.

A streamlined radiosynthetic methodology enables the precise sequential assembly of boronic ester precursors on diol resin, seamlessly integrating copper-mediated radioiododeboronation and azide-alkyne cycloaddition. This approach yields radioiodinated compounds with high radiochemical conversion (>90%) without requiring column purification until the final stage, thereby accelerating the efficient development of advanced radioiodinated molecular probes.
