CAS 18531-94-7: (+)-BINOL

Descripción:
(+)-BINOL, o 1,1'-bi-2-naftol, es un compuesto orgánico quiral caracterizado por sus dos anillos de naftaleno conectados por un enlace simple con grupos hidroxilo en las posiciones 1 y 1'. Es un sólido incoloro a amarillo pálido que es poco soluble en agua pero soluble en disolventes orgánicos como el etanol y el éter. El compuesto exhibe una fuerte actividad óptica debido a su naturaleza quiral, lo que lo convierte en un bloque de construcción importante en la síntesis asimétrica y un ligando clave en varios procesos catalíticos. (+)-BINOL puede participar en enlaces de hidrógeno debido a sus grupos hidroxilo, influyendo en su reactividad e interacciones con otras moléculas. Se utiliza ampliamente en la síntesis de catalizadores quirales y en el desarrollo de reacciones enantioselectivas, particularmente en el campo de la química orgánica. Además, sus derivados pueden servir como precursores para compuestos orgánicos más complejos, mostrando su versatilidad en aplicaciones sintéticas.

  • (R)-(+)-1,1'-Bi(2-naphthol), 99%

    CAS:
    It is used in biosynthetic preparation for enantioselective oxidation of naphthols to binaphthyldiols with horseradish peroxidase catalyst. A chiral auxiliary used in the catalytic asymmetric oxidation of sulfides to sulfoxides. Chiral lanthanide triflates formed from binaphthol serve as catalysts for asymmetric Diels-Alder reactions. Derivatives of binaphthol have recently found use in asymmetric Claisen rearrangements and asymmetric epoxidations.5 The lithium aluminum hydride derivative of these diols (BINAP-H) has been used extensively for the reduction of ketones. Chiral binapthol imminium salt precursor. Salts were used for an asymmetric epoxidation of olefins.

  • (R)-1,1'-Bi-2-Naphthol

    CAS:
    (R)-1,1'-Bi-2-Naphthol is an organic compound that is made from the hydrogenation of 2-naphthol. The sodium salts of this compound are chiral and can be used to synthesize racemic mixtures with a high degree of optical purity. The x-ray crystal structures of (R)-1,1'-Bi-2-Naphthol have been studied in detail and show that this molecule exhibits intermolecular hydrogen bonding interactions. It also has a steric interaction with the amine group which prevents rotation about the C3-C4 bond. Other interesting features include intramolecular hydrogen bonding interactions between the hydroxyl group and the alkanoic acid. This molecule also has a hydrophobic region consisting of three methyl groups that are connected to fatty acids.
