Herein, we report a novel strategy for the regioselective synthesis of aromatic and heteroaromatic 2,3-dihydrooxazoles from 2-alkynyl-1,3-dithianes and nitrones. This method exploits the 1,3-dithiane umpolung, nucleophilic cycloaddition, and rearrangement processes to achieve the rapid assembly of dihydrooxazole molecules. The regioselective method is extremely mild, achieving complete conversion within
在此,我们报告了一种从2-炔基-1,3-二噻烷和硝酮区域选择性合成芳香族和杂芳香族2,3-二氢恶唑的新策略。该方法利用 1,3-二噻烷 umpolung、亲核环加成和重排过程来实现二氢恶唑分子的快速组装。该区域选择性方法极其温和,在25℃空气下一分钟内即可实现高效率的完全转化。
