    通过迈克尔加成或顺序迈克尔加成和钯催化的 C-C 或 CN 交叉偶联制备了几种含有苯并 [b] 噻吩部分的新型氨基酸和脱氢氨基酸。迈克尔加成的底物是 N,N-双(叔丁氧羰基)脱氢丙氨酸 [Boc2-ΔAla-OMe] 和 N-(4-甲苯磺酰基)-N-(叔丁氧羰基)脱氢丙氨酸 [Tos-ΔAla( N-Boc)-OMe],亲核试剂是芳香族硫醇和 3-碘苄胺。将巯基苯并[b]噻吩直接添加到 Tos-ΔAla(N-Boc)-OMe 中,立体选择性地以良好的产率得到相应脱氢半胱氨酸的 E-异构体。当苯硫酚和 3-碘苄胺用作亲核试剂时,附加官能团(卤素或胺)的存在允许随后钯催化的与官能化苯并[b]噻吩(硼酸、卤素或胺)的交叉偶联反应。使用这种策略,以良好的收率获得了几种外消旋氨基酸和脱氢氨基酸衍生物,它们通过芳族间隔基连接到苯并 [b] 噻吩部分。(© Wiley-VCH Verlag GmbH &

    Recent studies have suggested that the alpha 7 nicotinic acetylcholine receptors play important roles in learning and memory. Herein, we describe our research of the structure-activity relationships (SAR) in a series of (S)-spiro[1-azabicyclo[2.2.2]octane-3,5'-oxazolidin]-2'-ones bearing various bicyclic moieties to discover novel alpha 7 receptor agonists. Through a number of SAR studies on the series, we have found out that inhibition of CYP 2D6 isozyme, which was a primary obstacle for the previously identified compound, was avoidable by the introduction of bicyclic moieties. Chemical optimization of the series led to the identification of a novel and potent alpha 7 nicotinic acetylcholine receptor partial agonist 23. This compound not only possessed high binding affinity (K-i) 3 nmol/L) toward the alpha 7 receptor but also showed agonistic activity even at a concentration of 0.1 mu mol/L. In addition, compound 23 improved cognition in several rat models, which might suggest the potential of the alpha 7 receptor partial agonist for the treatment of neurological disorders including cognitive dysfunction.

    Several novel amino acids and dehydroamino acids containing the benzo[b]thiophene moiety were prepared by Michael addition or sequential Michael addition and palladium-catalyzed C−C or C−N cross couplings. The substrates for Michael addition were the methyl esters of N,N-bis(tert-butyloxycarbonyl)dehydroalanine [Boc2−ΔAla−OMe] and N-(4-toluenesulfonyl)-N-(tert-butyloxycarbonyl)dehydroalanine [Tos−ΔAla(N-Boc)−OMe]
