The key steps included the Pd-catalyzed 3-dehydroxylation of 14-hydroxymorphine, S(N)2 substitution of Ts(-) by F(-), and CH(3)SO(2)OH-promoted rearrangement of the substituted morphinandiene. The dopamine binding affinity of this compound was also investigated on rat brain membranes, and as expected, this compound displayed high affinity and selectivity at the D(2) receptor.
[结构:见文字]。从蒂巴因以13个步骤合成2-氟-11-羟基-N-丙基诺拉啡4(2-F-11-OH-NPa),总产率为1.35%。关键步骤包括Pd催化的14-羟基吗啡的3-脱羟基反应,Ts(-)的S(N)2被F(-)取代以及CH(3)SO(2)OH促进的吗啡二烯的重排。还研究了该化合物在大鼠脑膜上的多巴胺结合亲和力,并且正如预期的那样,该化合物在D(2)受体上显示出高亲和力和选择性。
