  使用二异丙基氨基硼烷进行镍催化的苯甲醚衍生物中的碳氧键还原还原反应

  摘要：

  芳族环上甲氧基的催化除去使得该基团可用作芳族官能化反应的无痕活化和导向基团。尽管已经报道了几种用于苯甲醚衍生物的还原裂解的催化方法，但是所有方法仅适用于π-延伸的芳基醚，例如萘基和联苯醚，而单环芳基醚不能被还原。在本文中，我们报道了使用二异丙基氨基硼烷作为还原剂的镍催化的芳基醚中C–O键的还原裂解反应。与以前报道的方法不同，这种还原剂可在范围更广的芳基醚底物（包括带有各种官能团的单环和杂环醚）中有效地降低C-O键。

  This methodology provides facile access to butenolide tethered homotryptamines in good to excellent yields under operationally simple conditions and features a broad substrate scope. Overall, the reaction sequence involves the formation of three new bonds (two C–C and one C–O) in a nucleophilic cascade manner. Additionally, an intramolecular rearrangement of these derivatives to thermodynamically more
