Sugar-protected 6-halouridine derivatives underwent Suzuki–Miyaura cross-coupling reactions with arylboronic acids in the presence of palladium(II) acetate as a catalyst, triphenylphosphine as a ligand, and sodium carbonate as a base. This methodology is applicable to both the C5- and C6-position of uridine and provides a direct access for versatile uridine derivatives.
在乙酸钯(II)作为催化剂,三苯基膦作为配体和碳酸钠作为碱的存在下,糖保护的6-卤代吡啶衍生物与芳基硼酸进行了Suzuki-Miyaura交叉偶联反应。该方法学适用于尿苷的C5和C6位置,并为通用尿苷衍生物提供了直接途径。
