An unusual scission–rearrangement process, which couples radical and ionic reactions, was observed with galactofuranose derivatives. This one-pot procedure afforded, in good yields, highly functionalized 1,4-dioxanes, which could be considered as six-membered-ring sugar analogues. The synthesis of C-glycoside analogues is also possible with this methodology.(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451
在呋喃半乳糖衍生物中观察到了一种不寻常的断裂重排过程,该过程将自由基和离子反应结合起来。这种一锅法以良好的收率提供了高度官能化的 1,4-二恶烷,可以将其视为六元环糖类似物。使用这种方法也可以合成 C-糖苷类似物。 (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
