efficient and green protocol for the synthesis of 2-oxazolines by the reaction of aromatic nitriles with β-aminoalcohols using sulfur under solvent-free conditions. The reaction occurs via the Willgerodt–Kindler mechanism followed by transamidation and dehydrosulfuration. This methodology offers several advantages such as good yields, mild and practical reaction conditions, simple work-up procedure, and
图形摘要 摘要 我们报告了一种通过芳香腈与 β-氨基醇在无溶剂条件下使用硫反应合成 2-恶唑啉的高效绿色方案。该反应通过 Willgerodt-Kindler 机制发生,然后是转酰胺和脱硫。该方法具有收率好、反应条件温和实用、后处理过程简单、底物范围广等优点,使该过程简单、方便、环保。
