PROCEDURE

实验过程

Palmitoyl chloride (1.55 mL, 1.8 mmol) was added to a solution of nucleoside 28 in abs pyridine and the reaction mixture was stirred overnight at room temperature. The solution was then quenched with MeOH, evaporated to dryness, dissolved in dichloromethane and washed with saturated aq sodium bicarbonate and brine. The organic phase was dried over sodium sulfate and evaporated to dryness. The residue was purified by flash chromatography on silica (EtOAc-Hexanes 1:1) affording 0.5 g of 29 (yield, 65%).
