The dye-sensitized photooxygenation of furanosyl furans easily affords C- or O-glycosides with cis-α,β-unsaturated 1,4-dioxo aglycones. The reaction, performed on a ribofuranosyl furan, provides a useful new entry to a novel pyridazine C-nucleoside that can be achieved through a simple one-pot procedure.
呋喃糖基呋喃的染料敏化光氧化,得到易于C-或O-与顺苷- α,β -不饱和的1,4-二氧代糖苷配基。在呋喃核糖基呋喃核糖核酸上进行的反应为新型哒嗪C-核苷提供了一个有用的新入口,可以通过简单的一锅法实现。
