Abstract
Phosphorylated molecules, particularly phosphorylated carbohydrates, have garnered significant interest due to their distinct biological activities, driving an urgent demand for efficient phosphorylation strategies. Herein, the successful development of a SnCl2‐catalyzed protocol for the phosphorylation of alcohols and carbohydrates is demonstrated. Notably, the reaction efficiency is found to be critically dependent on the addition order of SnCl2 and N,N‐diisopropylethylamine, a phenomenon systematically investigated through mechanistic studies. A one‐pot sequential ketalization/phosphorylation strategy is established for polyol substrates, enabling streamlined access to phosphorylated derivatives. The versatility of this approach is further exemplified by achieving selective phosphorylation/phosphinoylation of carbohydrates.
