Axial-to-central chirality was transferred from BINOL to the P centre of the newly formed P-chirogenic compound. (nature.com)
Key to the success of our approach is the axial-to-central transfer of chirality from the BINOL structure to the phosphorus atom during the catalytic cross-coupling event. (nature.com)
Repeating unit1
Herein, we synthesized a water-soluble conjugated tubular host-namely, corral[4]BINOL-using a chiral 1,1'-bi-2-naphthol (BINOL) derivative as the repeating unit. (bvsalud.org)
Material1
The ready access to both mirror image forms (enantiomers) of the starting material and the easy recycling of the BINOL auxiliary group adds to the practicality of our method for generating P-chirogenic phosphorus compounds. (nature.com)
Range2
The ultrastrong binding strength, outstanding enantioselectivity, facile accessibility, together with the superior fluorescent and chiroptical properties, endow corral[4]BINOL with great potentials for a wide range of applications. (bvsalud.org)
Importantly, we found that a range of P-chirogenic phosphorus compounds and their derivatives can be synthesized as virtually single enantiomers. (nature.com)
Enantioselective3
A 1,1'-bi-2-naphthol (BINOL)-derived disulfonimide (DSI)-catalyzed enantioselective aza-Friedel-Crafts reaction between 1,3,5-trialkoxy benzenes and N-sulfonyl aldimines gives direct access to a series of chiral diarylmethylamines in good yields and good to excellent enantioselectivities (up to 97% ee).

This report describes the synthesis of a range of chiral polycyclic molecules (tricyclic to pentacyclic) from achiral polyene precursors by enantioselective proton-initiated polycyclization promoted by the 1:1 complex of o,o'-dichloro-BINOL and SbCl(5). (nih.gov)

Naphthalene1
Others are dimers of naphthalene derivatives such as 1,1'-bi-2-naphthol. (wikipedia.org)
Yields1
Alkylation of aldehyde , another carbon-carbon forming reaction, was also carried out in the presence of binaphthol derivatives with good yields and enantioselectivies. (edu.hk)
Synthesis1
This reaction provides a useful protocol for the direct synthesis of diarylmethylamine derivatives. (bvsalud.org)
Reaction2
In order to investigate the electronic and steric effect on this reaction, a series of binaphthol derivatives with electronic-donating groups or electronic-withdrawing groups at 6,6'-positions were synthesized. (edu.hk)
The process is practical as well as efficient, because the chiral ligand is both readily prepared from R,R- or S,S-BINOL and easily recovered from the reaction mixture by extraction. (nih.gov)
