How is (2S,3S,4S,5R,6R)-6-{[{[{[(2R,3S,4R,5R)-5-(2,4-Dioxo-3,4-dihydro-1(2H)-pyrimidinyl)-3,4-dihydroxytetrahydro-2-furanyl]methoxy}(hydroxy)phosphoryl]oxy}(hydroxy)phosphoryl]oxy}-3,4,5-trihydroxytetrahydro-2H-pyran-2-carboxylic acid (CAS: 2616-64-0) typically synthesized?

The compound (2S,3S,4S,5R,6R)-6-{[{[{[(2R,3S,4R,5R)-5-(2,4-Dioxo-3,4-dihydro-1(2H)-pyrimidinyl)-3,4-dihydroxytetrahydro-2-furanyl]methoxy}(hydroxy)phosphoryl]oxy}(hydroxy)phosphoryl]oxy}-3,4,5-trihydroxytetrahydro-2H-pyran-2-carboxylic acid (CAS: 2616-64-0) is typically synthesized through a multistep process involving the synthesis of the pyrimidinyl-furanyl intermediate, followed by the introduction of the phosphoryl groups via phosphorylation reactions. Common catalysts include Lewis acids and organocatalysts, and the overall yield is moderate to high, depending on the purity of the starting materials and reaction conditions.
