A strategy for the efficient metal-free C-O bond cleavage of ester using amines for the synthesis of substituted oxazoles was developed for the first time. The synthesis proceeded smoothly under metal-free conditions, combining C-O bond cleavage as well as C-N and C-O bond formation in one pot to yield desired products in moderate to excellent yields, and accommodated a wide range of functional groups and substrates.
首次开发了一种使用胺类进行酯的高效无金属C-O键裂解以合成取代恶唑的策略。该合成在无金属条件下顺利进行,将C-O键裂解以及C-N和C-O键形成一锅法进行,以中等至优异的产率得到所需产物,并且适用于广泛的官能团和底物。
