Used as a key intermediate in the synthesis of certain antiviral and anticancer agents, particularly in the development of nucleoside analogs. Its sulfonylpyrimidine structure, featuring a chiral (2S,3R)-3-methylpent-4-en-2-yl substituent, allows for selective modification in drug design, enhancing metabolic stability and target binding. Commonly employed in medicinal chemistry for constructing bioactive molecules that inhibit specific enzymes involved in viral replication or tumor growth. Also utilized in research settings to explore new pathways in heterocyclic compound development.
