  氨基杂环的脱氨基氯化

  摘要：

  对含杂原子芳族结构的选择性修饰需求量很大，因为它可以快速评估高级中间体中的分子复杂性。受自然界中脱氨酶选择性的启发，本文提出了一种简单的方法，可以将氨基杂环中的 NH 2基团视为掩蔽修饰句柄。借助简单的吡喃试剂和廉价的氯化物源，C( sp 2 )-NH 2可以转化为 C( sp 2)-Cl 键。该方法的特点是其广泛的官能团耐受性和底物范围，允许修饰超过 20 种不同类别的杂芳基基序（五元和六元杂环），具有许多敏感基序。NH 2以后期方式轻松转化为Cl，使从业者能够应用Sandmeyer-和Vilsmeier-型转化，而没有爆炸性和不安全的重氮盐、化学计量过渡金属或高氧化性和非选择性氯化剂的负担。
