Pd-Catalyzed kinetic resolution of benzylic alcohols: a practical synthesis of (R)-tomoxetine and (S)-fluoxetine hydrochlorides
摘要:
A convenient synthetic route to (R)-tomoxetine hydrochloride (90% ee) and (S)-fluoxetine hydrochloride (84% ee) is described. (S)-3-Phenyl-3-hydroxypropyl p-toluenesulphonate, the key intermediate, is obtained by the oxidative kinetic resolution of the corresponding racemic 3-phenyl-3-hydroxypropyl p-toluenesulphonate using (-)-sparteine/Pd(II)/O-2 (1 atm) catalytic system.

Structure based design led directly to 1,3-oxazinan-2-one 9a with an IC50 of 42 nM against 11β-HSD1 in vitro. Optimization of 9a for improved in vitro enzymatic and cellular potency afforded 25f with IC50 values of 0.8 nM for the enzyme and 2.5 nM in adipocytes. In addition, 25f has 94% oral bioavailability in rat and >1000× selectivity over 11β-HSD2. In mice, 25f was distributed to the target tissues

An imidazolidin-2-one chiralauxiliary mediated acetate aldol reaction was explored in the enantioselective synthesis of (S)-dapoxetine (SSRI). The diastereoselective aldol adduct was transformed to highly enantiopure (S)-dapoxetine with overall good yield.

α-disubstituted cyclic amino acidderivatives in medicinal chemistry urges for analogue design with improved pharmacokinetic properties. Herein, we disclose an electrochemical approach toward unnatural THF- and THP-containing amino acidderivatives that relies on anodic decarboxylation-intramolecular etherification of inexpensive and readily available N-acetylamino malonicacid monoesters under Hofer–Moest
α,α-二取代环状氨基酸衍生物在药物化学中的广泛应用迫切需要具有改进的药代动力学特性的类似物设计。在此,我们公开了一种针对非天然含THF和THP的氨基酸衍生物的电化学方法,该方法依赖于廉价且容易获得的N-乙酰氨基丙二酸单酯在Hofer-Moest反应条件下的阳极脱羧-分子内醚化。脱羧环化在恒定电流条件下在未分裂的细胞中在水性介质中进行,无需添加任何碱。在组织蛋白酶 K 抑制剂 balicatib 中,用含 THP 的氨基酸支架成功生物等排取代 1-氨基环己烷-1-羧酸亚基,有助于降低亲脂性,同时保留低纳摩尔酶抑制效力和相当的微粒体稳定性。
