, independently, is optionally substituted alkyl, alkenyl, cycloalkyl, cycloalkenyl, alkylsilyl, heterocycloalkyl, heterocycloalkenyl, aryl, aryloxy, or heteroaryl. The method can give enantioenriched propargylic alcohols with good enantioselective at low loading of MITH.
揭示了一种由2-吗啉基异冰片烷-10-硫醇(MITH)催化制备丙炔醇的方法,该方法包括在R3ZnR4和MITH的存在下,将R1CHO与R2CCH反应,其中R1、R2、R3和R4中的每一个,独立地,可以是可选取代的烷基、烯基、环烷基、环烯基、烷基硅基、杂环烷基、杂环烯基、芳基、芳氧基或杂芳基。该方法可以在MITH的低负载下提供具有良好对映选择性的对映富集的丙炔醇。
