第二代Grubbs钌催化剂与乙烯基氧基三甲基硅烷的反应可有效生成具有N-杂环卡宾(NHC)配体的纯氢化钌络合物,并具有明确的特征。该氢化钌络合物对末端烯烃的选择性异构化和1,6-二烯的环异构化显示出高催化活性。的这些反应Ñ -allyl- Ò -vinylaniline导致新的合成方法杂环如吲哚和3-亚甲基-2,3- dihydroindoles,这对于生物活性天然产物有用的合成子。这些程序解决了面向多样性的综合中的一个重要问题。
7-Chloro-5-hydroxy-1-[2-methyl-4-(2-methylbenzoylamino)benzoyl]-2,3,4,5-tetrahydro-1 H -1-benzazepine (OPC-41061): A potent, orally active nonpeptide arginine vasopressin V 2 receptor antagonist
benzazepine derivatives as orallyactivenonpeptide arginine vasopressin (AVP) V2 receptorantagonists. After the lead structure OPC-31260 was structurally evaluated and optimized, the introduction of the 7-Cl moiety on the benzazepine and 2-CH3 on the aminobenzoyl moiety enhanced its oral activity. The new AVP-V2 selective antagonist OPC-41061 was determined to be a potent and orallyactive agent.
