Product Description & Scientific Applications
(4-Boc-aminophenyl)boronic Acid is a Boc-protected aminophenylboronic acid for introducing a masked 4-aminophenyl unit into coupled aryl frameworks.
May contain small amounts of the cyclic anhydride 4-Boc-aminophenylboroxine. Under aqueous or basic coupling conditions the two forms re-equilibrate and the impact on yield is minor.
Applications and Reactions
Suzuki–Miyaura cross-coupling: couples with aryl, heteroaryl, or alkenyl electrophiles to give Boc-protected 4-aminobiaryl and related heteroaryl products.
Orthogonal protected-aniline handle: the boronic acid reacts at C–B while the Boc-protected amine is retained through many neutral or basic coupling conditions.
4-Aminobiaryl precursor: acid-mediated Boc removal after coupling reveals the corresponding aniline for downstream functionalisation.
Amide, sulfonamide, and urea diversification: the deprotected aniline provides a practical handle for late-stage derivatisation of coupled biaryl intermediates.
Rhodium-catalysed allylic substitution: documented as an arylboronic-acid partner in desymmetrisation of meso-cyclic allylic dicarbonates via SN2′-type C–C bond formation.
Protected boronate derivatives: precursor to pinacol, neopentyl glycol, and related boronate forms where improved handling or staged coupling is preferred.
