strategy. The iron(II)-catalyzed domino isomerization of 3-alkyl/aryl-4-arylisoxazoles provides a selective access to a wide range of structurally diverse highly substituted indole-3-carboxylates. The operational simplicity, high atom efficiency, and the use of stable starting materials and an inexpensive and low-toxicity catalyst are some of the attractive features of this tandem double ring-opening–ring-closure
摘要 铁(II)催化的3-烷基/芳基-4-芳基异恶唑的多米诺骨牌异构化提供了对各种结构多样的高度取代的吲哚-3-羧酸酯的选择通道。这种串联双开环-闭环策略的一些吸引人的特征是,操作简便,原子效率高,使用稳定的起始原料以及廉价且低毒的催化剂。 铁(II)催化的3-烷基/芳基-4-芳基异恶唑的多米诺骨牌异构化提供了对各种结构多样的高度取代的吲哚-3-羧酸酯的选择通道。这种串联双开环-闭环策略的一些吸引人的特征是,操作简便,原子效率高,使用稳定的起始原料以及廉价且低毒的催化剂。
