1,1′-Bi-2-naphthol (BINOL) is an organic compound that is often used as a ligand for transition-metal catalysed asymmetric synthesis. BINOL has axial chirality and the two enantiomers can be readily separated and are stable toward racemisation. The specific rotation of the two enantiomers is 35.5° (c = 1 in THF), … See more The organic synthesis of BINOL is not a challenge as such but the preparation of the individual enantiomers is. (S)-BINOL can be prepared directly from an asymmetric oxidative coupling of 2-naphthol See more Aside from the starting materials derived directly from the chiral pool, (R)- and (S)-BINOL in high enantiopurity (>99% enantiomeric excess) are two of the most inexpensive sources of chirality for organic synthesis, costing less than US$0.60 per gram when … See more • Shibasaki catalysts See more WebDec 11, 2014 · Silanediols incorporated into a BINOL framework are attractive catalysts, as they are readily accessible and highly customizable. Structural modifications of the BINOL backbone affect the reactivity and …
WebOtro efecto observable es la prevención de la rotación alrededor de un enlace sencillo dentro de una molécula. Por ejemplo, la molécula 1,1'-bi-2-naftol (BINOL) siempre está presente en una conformación retorcida debido al impedimento estérico de los átomos de hidrógeno entre los dos anillos (no mostrados).
