The synthesis of [14C]-labelled glycidyl ethers and the corresponding glycerol ethers is described for the monofunctional compounds 1-dodecanol and ortho-cresol and the bifunctional compounds 4,4′-dihydroxy-3,3′,5,5′-tetramethyl biphenyl and 1,6-hexanediol. The synthesis is based on reaction between the alcohol and [U-14C]-epi-chlorohydrin (1). The aromatic compounds have been converted to the corresponding
[14C]-标记的缩水甘油醚和相应的甘油醚的合成描述了单官能化合物 1-十二醇和邻甲酚和双官能化合物 4,4'-二羟基-3,3',5,5'-四甲基联苯和 1,6-己二醇。该合成基于醇与 [U-14C]-表氯醇 (1) 之间的反应。使用氢氧化钠将芳香族化合物转化为相应的缩水甘油醚,使用氯化锡 (IV) 作为催化剂将脂肪族化合物转化为相应的缩水甘油醚。因此,放射性标记的缩水甘油醚的产率在 50-80% 之间,化学纯度 >92%,放射化学纯度 >95%。缩水甘油醚的比活性对于单官能化合物约为 0·2 mCi/mmol,对于双官能化合物约为 0·4 mCi/mmol。
