    [GRAPHIC]A one-pot method for the asymmetric synthesis of tert-butanesulfinyl-protected amines is described. Condensation of aryl alkyl and dialkyl ketones with tert-butanesulfinamide followed by in situ reduction with the appropriate reagent provides either diastereomer of the sulfinamide products in good yields and with diastereomeric ratios of up to 99:1.

    energetically favorable 1,2-shift across the alkene followed by an irreversible C-H insertion to give cyclopentenone products. This reaction sequence overcomes typical challenges of counter-ion trapping and rearrangement reversibility of vinyl cations and has been used to study the migratory aptitudes of nonequivalent substituents in an uncommon C(sp2) to C(sp) vinyl cation rearrangement. The migratory aptitude
    路易斯酸促进了由β-羟基重氮酮生成不稳定的乙烯基阳离子,从而在烯烃上产生了能量上有利的1,2-转移,随后发生不可逆的CH插入,从而生成了环戊烯酮产物。此反应序列克服了对反离子捕获和乙烯基阳离子重排可逆性的典型挑战,已被用于研究非常见的C(sp2)对C(sp)乙烯基阳离子重排中非等价取代基的迁移能力。迁移倾向的趋势与其他阳离子重排中观察到的一致;最能稳定阳离子的取代基更容易迁移。但是,密度泛函理论计算表明情况更为复杂。乙烯基阳离子的一种构象异构体的形成中的选择性和由于乙烯基阳离子与相邻的羰基氧之间的静电相互作用而导致的面部选择性迁移穿过烯烃,共同决定了哪个基团迁移。当将这种方法应用于在α和β位置被不同取代的结构复杂的环戊烯酮的合成时,这项研究为预测​​迁移偏好提供了宝贵的见识。

  • Syntheses of 1,2-N-alkylimino-1,2,3,4-tetrahydronaphthalene derivatives and preparation of ring closed analog of salbutamol as a new .BETA.-adrenoceptor agent.

    A method for preparing 5-substituted 2-tertiary-alkylamino-6-hydroxy-1, 2, 3, 4-tetrahydro-1-naphthalenols was described. The method involves the preparation of 1-alkylamino-2-hydroxy-1, 2, 3, 4-tetrahydronaphthalenes from 2-bromo-1-hydroxy derivatives via 1, 2-epoxides followed by the transposition of 1-alkylamino and 2-hydroxy groups via the ring closure to 1, 2-aziridines. Formation of the epoxides and aziridines and the reaction of epoxides with amines were examined in detail. The ring-opening reaction of epoxides was regioselective and the attacking position of a nucleophile was not affected by the electronic effects of substituents on the benzene ring. Cyclization into aziridine rings was best accomplished by the Wenker method using a sulfur trioxide-triethylamine adduct as the sulfating agent. Using our process, trans-2-tert-butylamino-6-hydroxy-5-hydroxymethyl-1, 2, 3, 4-tetrahydro-1-naphthalenol (70) was synthesized as conformationally fixed analog of salbutamol.
