[Means for Solving the Problem]
The present invention is a quaternary ammonium salt compounds represented by formula (I), or a pharmaceutically acceptable salt thereof, with superior β32 adrenergic receptor agonist activity and muscarinic receptor antagonist activity.
conversion of substituted 1,3-cyclohexanediones to the alkyl ethers of resorcinol using a Pd/C–ethylene system is reported. In these reactions, ethylene works as a hydrogen acceptor. The efficient synthesis of resveratrol was achieved using this protocol as a key step. In addition, the direct formation of substituted resorcinols was carried out by adding K2CO3 into the reaction media.
据报道,使用Pd / C-乙烯系统将取代的1,3-环己二酮转化为间苯二酚的烷基醚。在这些反应中,乙烯充当氢受体。使用该方案作为关键步骤,可实现白藜芦醇的有效合成。另外,通过向反应介质中加入K 2 CO 3来直接形成取代的间苯二酚。

the first highly enantioselective Rh-catalyzed carboacylation of olefins via C-C bond activation of benzocyclobutenones. Good yields and excellent enantioselectivities (92-99% ee, 14 examples) were obtained for substrates with various steric and electronic properties. In addition, fully saturated poly-fused rings were prepared from the carboacylation products through a challenging catalytic reductive
在这里,我们报告了第一个通过苯并环丁烯酮的 CC 键活化对烯烃进行高度对映选择性的 Rh 催化碳酰化。对于具有各种空间和电子特性的基材,获得了良好的产率和出色的对映选择性(92-99% ee,14 个实例)。此外,通过具有挑战性的催化还原脱芳构化方法,由碳酰化产物制备了完全饱和的聚稠环。这些研究提供了一种独特的方法来制备手性碳骨架,这些骨架是用传统方法难以获得的。
