An expedient one-pot stereo- and regioselective synthesis of 2-iodo-nucleosides from protected glycals and nucleobases using easily available iodine and hexamethyldisilane as halogenating, and silylating agents respectively has been developed. Most of the products synthesized characterized as diastereomerically pure β-1,2-trans-diequitorial nucleosides hitherto not reported. The studies unveil the cogent antiviral activity of these newly synthesized nucleoside derivatives against the Japanese Encephalitis Virus (flavivirus) in the Vero cell line.
已开发出一种便捷的一锅法立体和区域选择性合成方法,该方法使用易于获得的碘和六甲基二硅烷分别作为卤化剂和硅烷化剂,从受保护的缩水甘油醛和核碱基合成2-碘代核苷。所合成的大多数产物被表征为非对映体纯的β-1,2-反式-双赤道核苷,这是迄今尚未报道过的。这些研究揭示了这些新合成的核苷衍生物在Vero细胞系中对日本脑炎病毒(黄病毒)具有较强的抗病毒活性。
