design: A cinchona alkaloid/TiIV‐catalyzed enantioselective tandem enamine–trifluoropyruvate condensation–cyclization reaction provides a robust method for the construction of small heterocyclic molecules with a quaternary trifluoromethylated carbon center (see scheme). The series of products are attractive templates and were readily converted to drug‐like trifluoromethylated heterocycles by conventional
药物设计:金鸡纳生物碱/ Ti IV催化的对映选择性串联烯胺-三氟丙酮酸缩合-环化反应为构建具有季三氟甲基化碳中心的小杂环分子提供了一种可靠的方法(参见方案)。该系列产品是有吸引力的模板,可通过常规方法轻松转化为药物样的三氟甲基化杂环。
