The present invention relates to antithrombotic compounds 2-alkyl aryl sulphonyl-1,2,3,4,-tetrahydro-9H-pyrido(3,4-b)indole-3-carboxylic acid esters/amides, pharmaceutically acceptable salts and compositions thereof to be used in the treatment of intravascular thrombosis such as myocardial ischemia and stroke. The compound has the following general structure
wherein R represents methyl ester or amide and R
1
represents alkyl, aryl and heteroaryl moiety.
safe and convenient open-flask copper-catalyzed selective oxidation/functionalization methodology for tetrahydrocarbolines and tetrahydro-β-carbolines that employs atmospheric O2 as the terminal oxidant. The system is applicable to oxidative rearrangement of tetrahydro-β-carbolines, tetrahydrocarboline oxidation to α-alkoxy carbazoles and spirooxindoles, and Witkop oxidation. Mechanistic experiments indicated
我们报告了一种使用大气 O 2作为终端氧化剂的四氢咔啉和四氢-β-咔啉的安全且方便的开瓶铜催化选择性氧化/功能化方法。该体系适用于四氢-β-咔啉的氧化重排,四氢咔啉氧化成α-烷氧基咔唑和螺氧吲哚,以及Witkop氧化。机械实验表明,单电子氧化过程负责可调选择性控制。这种铜催化协议代表了吲哚氧化领域的重大进步。
