(4-(1-(Hydroxymethyl)cyclopropyl)phenyl)boronic Acid

This hybrid molecular architecture crystallizes as a white to pale yellow powder,exhibiting a notably high melting point of 176-180°C,indicative of strong intermolecular interactions likely involving boronic acid dimerization and hydrogen bonding from the hydroxymethyl group.Its predicted boiling point exceeds 380°C.The compound demonstrates a characteristic solubility profile of polar organoborons:negligible in water but highly soluble in dipolar aprotic solvents like THF and DMF.It requires stringent storage under inert gas at 2-8°C to prevent progressive oxidation of the benzylic alcohol and hydrolysis/dehydration of the boronic acid moiety.

This molecule is a strategically engineered bifunctional building block that merges a conformationally locked,strained cyclopropane unit with a versatile arylboronic acid.The cyclopropane,bearing a hydroxymethyl group,acts as a rigid,three-dimensional spacer that projects the boron handle with precise spatial control.This unique combination transforms it from a simple coupling partner into a sterically defined,vectorial synthon,enabling the construction of complex architectures where both the coupling point and the backbone geometry are pre-programmed.

1.Pharmaceutical Synthesis

Employed in the design of proteolysis-targeting chimeras(PROTACs)and molecular glues.The rigid cyclopropane linker provides optimal distance and orientation between target-binding and E3 ligase-recruiting warheads,improving degradation efficiency.The boronic acid allows for rapid diversification of the aromatic component via Suzuki coupling during optimization cycles.

2.Agrochemical R&D

Serves as a precursor for novel systemic insecticides with improved photostability.The cyclopropyl group mimics natural insect hormone substructures,while the boronic acid facilitates the attachment of heterocyclic pharmacophores that interact with insect GABA receptors,leading to compounds with reduced vertebrate toxicity.

3.Functional Material Synthesis

Utilized as a monomer in Suzuki polycondensation reactions to produce conjugated polymers with intrinsic backbone kinks.The cyclopropane unit introduces controlled torsion into the polymer chain,modulating band-gap energy and solid-state packing for use in nonlinear optical materials and as morphology controllers in organic photovoltaic blends.

4.Organic Synthesis Building Block

A valuable substrate for studying strain-release driven transformations.The boronic acid can participate in cross-coupling,after which the strained ring can be opened via radical,oxidative,or transition-metal catalyzed pathways to access 1,3-difunctionalized propane derivatives,offering a divergent route to linear chains from a cyclic precursor.
