A simple method to convert readily available carboxylic acids into sulfinate salts by employing an interrupted Barton decarboxylation reaction is reported. A medicinally oriented panel of ten new sulfinate reagents was created using this method, including a key trifluoromethylcyclopropanation reagent, TFCS‐Na. The reactivity of six of these salts towards CH functionalization was field‐tested using
报道了一种通过使用间断的 Barton 脱羧反应将容易获得的羧酸转化为亚磺酸盐的简单方法。使用这种方法创建了一个由十种新亚磺酸盐试剂组成的医学导向面板,其中包括一种关键的三氟甲基环丙烷化试剂 TFCS-Na。使用几种不同类别的杂环对这些盐中的六种对C H 官能化的反应性进行了现场测试。

for programmable and stereospecific installation of these alkyl bioisosteres. The ability of this method to simplify retrosynthetic analysis is exemplified by the improved synthesis of multiple medicinally relevant scaffolds. Experimental studies and theoretical calculations for the mechanism of this sulfur chemistry reveal a ligand-coupling trend under alkyl Grignardactivation via the sulfurane intermediate
