  A general and convenient route to oxazolyl ligands

  摘要：

  A diverse range of chiral and achiral oxazolyl ligands, which have many applications including catalysis and luminescent devices, are synthesized simply in three steps from readily available and inexpensive phenol and amino alcohol starting materials. The method can be applied to ligands with electron-donating/-withdrawing and sterically demanding/undemanding substituents, and can conveniently be scaled up to >25 g of product.

  oxazoline production. Herein, we report a triflic acid (TfOH)-promoted dehydrative cyclization of N-(2-hydroxyethyl)amides for synthesizing 2-oxazolines. This reaction tolerates various functional groups and generates water as the only byproduct. This method affords oxazoline with inversion of α-hydroxyl stereochemistry, suggesting that alcohol is activated as a leaving group under these conditions

  2-恶唑啉是许多天然产物、药物和功能共聚物中的常见部分。目前合成2-恶唑啉的方法主要依靠化学计量脱水剂或特定催化剂促进的催化脱水。这些条件要么产生化学计量的废物，要么需要强制共沸回流条件。因此，促进脱水环化同时不产生副产物的实用且稳健的方法将对恶唑啉生产具有吸引力。在此，我们报告了三氟甲磺酸 (TfOH) 促进的 N-(2-羟乙基) 酰胺脱水环化合成 2-恶唑啉。该反应容忍各种官能团并产生水作为唯一的副产物。该方法提供了 α-羟基立体化学反转的恶唑啉，表明在这些条件下酒精作为离去基团被激活。此外，还提供了直接从羧酸和氨基醇合成 2-恶唑啉的一锅法合成方案。
