  摘要：

  通过三种路线合成了一系列N-取代的2-氨基-5,6-二羟基-1,2,3,4-四氢-1-萘酚(1)，它们是肾上腺素儿茶酚胺的构象刚性衍生物；即，最终步骤为1)1-羰基的还原，2)2-氨基的还原烷基化进行N-取代，或3)除去儿茶酚部分的保护基团的合成路线。通过立体选择性反应或通过柱色谱或分级结晶分离每种立体异构体来制备1的几对1、2-顺式和反式异构体。因此，通过用硼氢化钠还原2-氨基-5,6-二苄氧基-3,4-二氢-1(2H)-萘酮(13)得到反式氨基醇(9-反式)，而顺式异构体(9- cis)是通过氮丙啶中间体从7,8-二苄氧基-1,2-二氢萘(19)获得的。 1 种中的几种表现出优于 l-异丙肾上腺素的优异 β2-肾上腺素受体活性，反式衍生物比顺式异构体更有效。

  Aspects of the present disclosure include conformationally restricted analogs of catecholamine type compounds (e.g., isoprenaline, adrenaline, noradrenaline) which activate β2AR with high selectivity over β1AR. The subject beta-2 selective adrenergic receptor agonist compounds may serve as bronchiodilators and find use in the treatment of a variety of bronchoconstrictive diseases and conditions. Also provided are compositions and methods for treating preterm labor. A method of treating acute asthma including administration of a subject compound to a subject in need thereof is provided. The subject method can provide for reduced undesirable side effects associated with non-selective β-adrenergic receptor agonism, such as inotropic and chronotropic effects that leads to elevated blood pressure. The compounds can also be used to prevent or treat heart failure. Kits and compositions for practicing the subject methods are also provided.

  A series of N-substituted 2-amino-5, 6-dihydroxy-1, 2, 3, 4-tetrahydro-1-naphthalenols (1), which are comformationally rigid derivatives of adrenergic catecholamine, were synthesized via three routes ; namely, the synthetic route in which the final step is 1) the reduction of 1-carbonyl group, 2) N-substitution by reductive alkylation of 2-amino group, or 3) removal of protecting groups of the catechol moiety. Several pairs of 1, 2-cis and trans isomers of 1 were prepared by stereoselective reactions or by separation of each stereoisomer with column chromatography or fractional crystallization. Thus, transamino alcohol (9-trans) was afforded by reduction of 2-amino-5, 6-dibenzyloxy-3, 4-dihydro-1 (2H)-naphthalenone (13) with sodium borohydride, while the cis isomer (9-cis) was obtained from 7, 8-dibenzyloxy-1, 2-dihydronaphthalene (19) via an aziridine intermediate. Several of 1 exhibited excellent β2-adrenoceptor activity superior to l-isoproterenol, the trans derivative being more potent than the cis isomer.
