摘要

报告了一种制备新型 O-二氟烷基羟胺氟化官能团（又称 FON）的高效策略。通过化学和区域选择性无金属氢醚化型加成法，一步合成了这种具有重要药用价值的 β-苯乙基醚支架类似物，其结合了 gem-difluoro 和 N-O 两个分子。如图所示，这种独特的反应模式可用于多种底物范围，并可应用于克级合成和位点选择性氘结合。最后，还提供了对布伦司特酸催化的机理理解。

FON: An Innovative Fluorinated Group via Hydroetherification-Type Reactivity

An efficient strategy for preparing the novel O-difluoroalkylhydroxylamine fluorinated functional group, coined FON, is reported. This analogue of medicinally important β-phenethyl ether scaffolds in uniting gem-difluoro and N–O moieties is synthesized in one step via chemo- and regioselectivity metal-free hydroetherification-type additions. As shown, this unique mode of reactivity is realized for a diverse substrate scope and applied to gram-scale synthesis and site-selective deuterium incorporation. Lastly, a mechanistic understanding with implications in Brønsted acid catalysis is offered.

期刊介绍： Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
