Herein, we report a microwave-assisted synthesis of 2-oxazolines from a carboxylic acid and amino alcohol by using dehydrating reagent carbonyl diimidazole (CDI). The developed methodology was successfully utilized for the synthesis of key intermediate oxazoline 2k (methyl 2-(2-hydroxyphenyl)-4,5-dihydrooxazole-4-carboxylate) of natural products Mycobactin S, Mycobactin T, and Spoxazomicin C. The salient
在此,我们报告了使用脱水试剂羰基二咪唑 (CDI) 从羧酸和氨基醇中微波辅助合成 2-恶唑啉的方法。所开发的方法成功地用于合成天然产物 Mycobactin S、Mycobactin T 和 Spoxazomicin C 的关键中间体恶唑啉2k (2-(2-羟基苯基)-4,5-二氢恶唑-4-羧酸甲酯)。该合成方法具有反应时间短、收率高、一锅法合成、反应条件不苛刻等优点。
