摘要
5-[4,5-C-13(2)]- and 5-[1,5-C-13(2)]Aminolevulinic acid (ALA) have been synthesized by the Gabriel condensation of potassium phthalimide with ethyl bromo [1,2-C-13(2)]acetate (derived from [1,2-C-13-]acetic acid) or ethyl bromo[2-C-13]- acetate (derived from sodium [2-C-13]acetate), followed by conversion to the chloride, coupling reaction with 2-ethoxycarbonylethylzinc iodide derived from ethyl 3-iodopropionate or 2-methoxy[C-13]carbonylethylzinc iodide derived from methyl 3-iodo[1-C-13]propionate (generated from potassium [C-13]cyanide), and hydrolysis.
