binding to Na+,K+-ATPase, is described. The key step involved a cyclization to the isoquinoline ring under Pictet-Gams conditions which was best performed with the 6-hydroxy group protected as the benzyl ether. When an unsaturated ester group was present in position 4 of the 1-benzyl group, this was best introduced before the cyclization step, since the IIeck reaction on 1-(4-bromobenzyl)-6-hydroxyisoquinoline
描述了1-(4-取代的)苄基-6-羟基异喹啉的合成,该合成将在与Na +,K + -ATPase结合的特定3 H-哇巴因的置换中进行评估。关键步骤涉及在Pictet-Gams条件下环化成异喹啉环,最好是将6-羟基作为苄基醚进行保护。当1-苄基的4位上存在不饱和酯基时,最好在环化步骤之前引入,因为1-(4-溴苄基)-6-羟基异喹啉(8)与丙烯酸衍生物的IIeck反应是并非在所有情况下都成功。
