    with sodium methoxide gave 7β-methoxyneopine (9). Similar reactions were performed with 14β-bromo-5β-methylcodeine (4), yielding the corresponding 5β-methyl derivatives 6, 8 and 10. Acetylation of 3 and 4 gave 6α-O-acetyl-14β-bromocodeine (11) and its 5β-methyl analogue 12, respectively, from which the ortho esters 13 and 14 were obtained after treatment with methanol. Acid hydrolysis of 13 or, better

    5β-butylthebaine (4), was obtained from thebaine (1) after reaction with butyllithium and ethyl iodide. With butyllithium and diethyl sulfate, thebaine yielded 5β-ethylthebaine (3), 5β, 10α-diethylthebaine (5), and 5β, 10α, 10β-triethylthebaine (6). The ratio of the compounds (3:4 and 3:5:6) depended on the excess of reagents used. Employing the reversed sequence of addition of reagents, that is, first diethyl
    5β-Ethylthebaine (3) ,具有5β-butylthebaine一起(4) ,从蒂巴因获得(1)与丁基和乙基反应后。用丁基硫酸二乙酯蒂巴因制得5β-乙基蒂巴因(3),5β,10α-二乙基蒂巴因(5)和5β,10α,10β-三乙基蒂巴因(6)。化合物的比例(3:4和3:5:6)取决于所用试剂的过量。利用添加试剂的顺序相反的顺序,首先是硫酸二乙酯,然后是丁基,我们从5β-乙基蒂巴因( 5,10-二乙基蒂巴因(5)和5β-甲基-10α-乙基蒂巴因(8)制备了3)和5β-甲基蒂巴因(7)。这些烷基化反应是根据Pearson的硬-软酸碱理论进行讨论的。

    reaction of 7-chloro-6-demethoxythebaine (8) and 7-chloro-5β-methyl- -6-demethoxythebaine (14) each with ethyl acrylate yielded four (14:6:4:1) and three adducts (15:4:1), respectively. The main adduct from diene 8 was the ethyl 6α,14α-ethenoisomorphinan-7α- -carboxylate 15, while diene 14 afforded the ethyl 6β,14β-ethenomorphinan-8β-carboxylate congener 17 in which the dienophile has reacted from the opposite

    Novel 6-ketolevorphanol analogs with diverse substitution patterns at ring C were synthesized and their binding affinities at the μ,δ and κ opioid receptors were investigated. The in vitro activity of the new analogs was then evaluated in the functional assay based on the electrically-stimulated contractions of the mouse ileum. It was shown that analogs with Δ7,8 bond had no significant potency at any of the opioid receptor types. In contrast, analogs with the saturated ring C were either potent κ agonist or antagonist depending on the absence or presence of the hydroxyl group in position 14.
    我们合成了具有不同C环取代模式的新型6-酮左啡诺类似物,并研究了它们在μ、δ和κ阿片受体上的结合亲和力。然后,我们基于小鼠回肠的电刺激收缩功能测定法评估了这些新类似物的体外活性。结果表明,具有Δ7,8键的类似物在任何阿片受体类型中均没有显著的效力。相反,具有饱和C环的类似物要么是强效κ激动剂,要么是强效κ拮抗剂,这取决于
