取代杯[6]芳烃的制备及在~(18)F-FET制备中的应用
本工作制备了相转移催化剂取代杯[6]芳烃:对磺酸杯[6]芳烃和对叔丁基杯[6]芳烃,并以其为催化剂进行了18F-FET的制备。结果表明,对磺酸杯[6]芳烃作催化剂不仅能够催化FET前体的19F取代反应,而且能够催化FET前体对(对甲苯磺酸酯)乙基苯甲酰(BOC)氨基酸酯的18F标记反应,放化产率为11%。而对叔丁基杯[6]芳烃对催化FET前体的19F取代反应和18F的标记反应均没有催化活性。对磺酸杯[6]芳烃的催化作用可能与它的磺酸基参与络合反应,增大了杯[6]芳烃极性等因素有关。虽然对磺酸杯[6]芳烃催化FET前体的放化产率远低于Kryptofix 2.2.2,但该研究对优化条件找出更好的取...

Summary: | 本工作制备了相转移催化剂取代杯[6]芳烃:对磺酸杯[6]芳烃和对叔丁基杯[6]芳烃,并以其为催化剂进行了18F-FET的制备。结果表明,对磺酸杯[6]芳烃作催化剂不仅能够催化FET前体的19F取代反应,而且能够催化FET前体对(对甲苯磺酸酯)乙基苯甲酰(BOC)氨基酸酯的18F标记反应,放化产率为11%。而对叔丁基杯[6]芳烃对催化FET前体的19F取代反应和18F的标记反应均没有催化活性。对磺酸杯[6]芳烃的催化作用可能与它的磺酸基参与络合反应,增大了杯[6]芳烃极性等因素有关。虽然对磺酸杯[6]芳烃催化FET前体的放化产率远低于Kryptofix 2.2.2,但该研究对优化条件找出更好的取代杯[6]芳烃催化剂具有重要的指导意义。 |
