The Ruppert–Prakash reagent is the most powerful and well-documented reagent for trifluoromethylation. Despite its versatility, no general method exists for its use in a flow system. Here we report the first flow trifluoromethylation of carbonyl compounds and its utility for drug synthesis of efavirenz and HSD-016, including preliminary results of enantioselective variants.
鲁伯特-普拉卡什(Ruppert-Prakash)试剂是用于三氟甲基化的功能最强大且文献充分的试剂。尽管它具有通用性,但在流动系统中没有通用的方法可以使用。在这里,我们报告了羰基化合物的第一个三氟甲基化流动及其在依非韦伦和HSD-016的药物合成中的效用,包括对映选择性变体的初步结果。
