This chemical, featuring a pyrimidine core with a 4-chloro substituent, a 2-(3-hydroxypyrrolidino) group, and a 5-boronic acid moiety, is widely used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions. It serves as a key building block for creating complex molecules, especially in pharmaceutical research and development. The boronic acid group enables efficient coupling with aryl or vinyl halides, facilitating the formation of carbon-carbon bonds, while the chloro group allows for further functionalization. This makes it valuable in the synthesis of biologically active compounds, such as drug candidates targeting various diseases. The 3-hydroxypyrrolidino group may enhance stability and water solubility, improving its utility in diverse reaction conditions. Additionally, it is utilized in material science for designing advanced organic materials with specific electronic or structural properties. Its versatility and reactivity make it a crucial component in modern chemical synthesis.
