Isopropoxyboronic acid pinacol ester

Description:

Isopropoxyboronic acid pinacol ester, with the CAS number 61676-62-8, is an organoboron compound characterized by the presence of a boronic acid functional group esterified with isopropanol and pinacol. This compound typically appears as a colorless to pale yellow liquid or solid, depending on its purity and form. It is known for its utility in organic synthesis, particularly in the formation of carbon-carbon bonds through cross-coupling reactions, such as Suzuki-Miyaura coupling. The presence of the boron atom allows for the formation of stable complexes with various nucleophiles, enhancing its reactivity. Isopropoxyboronic acid pinacol ester is generally soluble in organic solvents like dichloromethane and ether, but less soluble in water due to its hydrophobic characteristics. Safety considerations include handling it with care, as boron compounds can be irritants. Overall, this compound serves as a valuable intermediate in the synthesis of pharmaceuticals and agrochemicals, showcasing the versatility of boron chemistry in modern organic synthesis.

2-Isopropoxy-4,4,5,5-tetramethyl-1,3,2-dioxaborolane is a synthetic chemical that has been shown to have antiviral activity against influenza virus and inhibit the synthesis of proteins in cancer cells. It inhibits the influenza virus from replicating by binding to the viral RNA polymerase and preventing it from transcribing viral RNA into proteins. 2-Isopropoxy-4,4,5,5-tetramethyl-1,3,2-dioxaborolane also binds to the boronic ester group of enzymes that are involved in plant metabolism and can be used as an herbicide. This chemical is synthesized by reacting boric acid with trimethoxysilane in an acidified water solution. The reaction produces hydrochloric acid which reacts with trimethoxysilane to form silanols. The silanols react with boric acid to produce 2
