  Palladium(II)‐Catalyzed Nondirected Late‐Stage C(sp2)–H Deuteration of Heteroarenes Enabled Through a Multi‐Substrate Screening Approach

  摘要：

  The importance of deuterium labelling in a variety of applications, ranging from mechanistic studies to drug‐discovery, has spurred immense interest in the development of new methods for its efficient incorporation in organic, and especially in bioactive molecules. The five‐membered heteroarenes at the center of this work are ubiquitous motifs in bioactive molecules and efficient methods for the deuterium labelling of these compounds are therefore highly desirable. However, the profound differences in chemical properties encountered between different heteroarenes hamper the development of a single set of broadly applicable reaction conditions, often necessitating a separate optimization campaign for a given type of heteroarene. In this study we describe the use of a multi‐substrate screening approach to identify optimal reaction conditions for different classes of heteroarenes from a minimal number of screening reactions. Using this approach, four sets of complementary reaction conditions derived from our dual ligand‐based palladium catalysts for nondirected C(sp2)–H activation were identified, that together enable the deuteration of structurally diverse heteroarenes, including bioactive molecules.

  杂芳烃的空间控制 CH 烯化。

  摘要：

  由于自然界和生物活性化合物中多取代杂芳烃的普遍存在，杂芳烃的区域选择性官能化是一个非常有吸引力的合成靶点。一些取代模式仍然具有挑战性：虽然已经报道了 3 取代五元杂芳烃的 C2 选择性烯化的高效方法，但获得 5 烯化产物的类似方法仍然受到较差的区域选择性和/或使用要求的限制。过量的有价值的杂芳烃起始材料。在此，我们报道了使用杂芳烃作为限制试剂的空间控制的CH烯化反应。该方法能够实现多种杂芳烃的高度 C5 选择性烯化，并被证明可用于后期官能化。

  substituted heteroarenes in nature and bioactive compounds. Some substitution patterns remain challenging: While highly efficient methods for the C2‐selective olefination of 3‐substituted five‐membered heteroarenes have been reported, analogous methods to access the 5‐olefinated products have remained limited by poor regioselectivities and/or the requirement to use an excess of the valuable heteroarene starting
