The use of crown ethers for a phase transfer-catalyzed synthesis of heteroaromatic glycosides of N-acetylglucosamine was studied. The solid-liquid system and catalysis by 15-crown-5 were found to provide for both the 100% conversion of α-D-glucosaminyl chloride peracetate and a high reaction rate. The interaction of α-D-glucosaminyl chloride peracetate and oxadiazole and triazole mercapto derivatives
研究了冠醚在相转移催化合成 N-乙酰氨基葡萄糖的杂芳族糖苷中的应用。发现固液系统和 15-crown-5 催化可提供 100% 的 α-D-氨基葡萄糖过乙酸酯转化率和高反应速率。在无水碳酸钾和冠醚存在下,在室温下,在乙腈中进行的 α-D-氨基葡萄糖过乙酸酯与恶二唑和三唑巯基衍生物的相互作用会导致 S- 和 N-糖苷。合成的化合物的结构通过X-射线分析和13C和1H NMR光谱证实。
