[1,1'-Biphenyl]-3-methanol, 3'-hydroxy- (CAS No. 176212-54-7): An Overview of Its Structure, Properties, and Applications

[1,1'-Biphenyl]-3-methanol, 3'-hydroxy- (CAS No. 176212-54-7) is a compound that has garnered significant attention in the fields of organic chemistry and medicinal chemistry due to its unique structure and potential biological activities. This article provides a comprehensive overview of the compound, including its chemical structure, physical properties, synthesis methods, and recent research findings.

Chemical Structure and Properties

[1,1'-Biphenyl]-3-methanol, 3'-hydroxy- is a biphenyl derivative with a hydroxyl group at the 3' position and a methanol group at the 3 position of the biphenyl ring. The biphenyl core consists of two benzene rings connected by a single bond, which allows for a range of conformational flexibility. The presence of the hydroxyl and methanol groups introduces polarity and hydrogen bonding capabilities, making this compound interesting for various applications.

The molecular formula of [1,1'-Biphenyl]-3-methanol, 3'-hydroxy- is C₁₄H₁₄O₂, with a molecular weight of approximately 206.26 g/mol. It is a white crystalline solid at room temperature and is soluble in common organic solvents such as ethanol, methanol, and dimethyl sulfoxide (DMSO). The compound exhibits moderate stability under standard laboratory conditions but may degrade upon exposure to strong acids or bases.

Synthesis Methods

The synthesis of [1,1'-Biphenyl]-3-methanol, 3'-hydroxy- can be achieved through several routes. One common method involves the coupling of 3-hydroxybenzaldehyde with phenylboronic acid using a palladium-catalyzed Suzuki coupling reaction. The resulting biphenyl intermediate can then be reduced to form the methanol group using a suitable reducing agent such as sodium borohydride (NaBH₄) or hydrogen gas in the presence of a palladium catalyst.

An alternative approach involves the reaction of 3-hydroxybenzyl chloride with phenylmagnesium bromide to form the corresponding Grignard reagent, which can then be hydrolyzed to yield the desired product. Both methods have been reported in the literature and offer different advantages in terms of yield and purity.
