Ammonium chloride promotes the selective formation of monosubstituted ureas under microwave irradiation. Most nucleophiles, acid-labile functionalities, and protecting groups are well tolerated in this reaction. By avoiding transition metals and mineral acids, this methodology offers a more sustainable alternative for the synthesis of monosubstituted ureas and their analogs.
氯化铵在微波辐射下促进单取代脲的选择性形成。大多数亲核试剂、酸不稳定官能团和保护基团在该反应中具有良好的耐受性。通过避免过渡金属和无机酸,该方法为合成单取代脲及其类似物提供了一种更可持续的替代方案。
