GRAPHICAL ABSTRACT ABSTRACT The synthesis of nebularine and its analogs has been achieved via oxidative desulfuration in H2O for the first time. With 50% HNO3 as an oxidant and solvent, 18 products were obtained in good yields (70%–94%). The oxidative desulfuration system could tolerate different functional groups including fluoro, chloro, amino, alkyl, allyl, ribosyl, deoxyribosyl, and arabinofuranosyl
图形摘要 摘要 nebularine 及其类似物的合成首次通过在 H2O 中氧化脱硫实现。以 50% HNO3 作为氧化剂和溶剂,以良好的收率 (70%–94%) 获得了 18 种产物。氧化脱硫系统可以耐受不同的官能团,包括氟、氯、氨基、烷基、烯丙基、核糖基、脱氧核糖基和阿拉伯呋喃糖基。更重要的是,药物 nebularine 可以在 20 g 的规模上成功获得,这使得该路线对工业应用更具吸引力。
