摘要:

AbstractNedocromil sodium labelled with carbon‐14 has been prepared by a Claisen reaction between diethyl [1,2‐14C]‐ethanedioate and methyl 6‐ethanoyl‐1‐ethyl‐1,4‐dihydro‐7‐hydroxy‐4‐oxo‐8‐propylquinoline‐2‐carboxylate. The2H‐ and3H‐labelled materials are readily prepared by rhodium(III) chloride catalysed exchange with the appr
