In the isomeric series of 12 racemic topologically rigid N-methyl analogues of oxide-bridged phenylmorphans, all but two of the racemates, the ortho- and para-b-oxide-bridged phenylmorphans 20 and 12, have remained to be synthesized. The b-isomers were very difficult to synthesize because of the highly strained 5,6-trans-fused ring junction that had to be formed. Our successful strategy required functionalization
在 12 种外消旋拓扑刚性 N-甲基氧化物桥接苯基吗喃类似物的异构系列中,除了两种外消旋物,邻位和对位-b-氧化物桥接苯基吗喃 20 和 12 外,所有其他化合物都有待合成。由于必须形成高度应变的 5,6-反式融合环结,b-异构体非常难以合成。我们成功的策略需要使用吸电子硝基将芳环上的氟原子的对位(或邻位)官能化以激活该氟。外消旋 N-苯乙基类似物 24 和 16 是 [(35) S] GTPgammaS 测定中中等有效的 kappa 受体拮抗剂。
