Title: Tetraethylene glycol promoted two-step, one-pot rapid synthesis of indole-3-[1-11C]acetic acid

An operationally friendly, two-step, one-pot process has been developed for the rapid synthesis of carbon-11 labeled indole-3-acetic acid ([11]IAA or [11]auxin). By replacing an aprotic polar solvent with tetraethylene glycol, nucleophilic [11]cyanation and alkaline hydrolysis reactions were performed consecutively in a single pot without a time-consuming intermediate purification step. The entire production time for this updated procedure is 55 min, which dramatically simplifies the entire synthesis and reduces the starting radioactivity required for a whole plant imaging study.
