A novel chiral 1,5-N,N-bidentate ligand based on a spirocyclic pyrrolidine oxazoline backbone was designed and prepared, and it coordinates CuBr in situ to form an unprecedented catalyst that enables efficient oxidative cross-coupling of 2-naphthols. Air serves as an external oxidant and generates a series of C1-symmetric chiral BINOL derivatives with high enantioselectivity (up to 99 % ee) and good yield (up to 87 %). This approach is tolerant of a broader substrates scope, particularly substrates bearing various 3- and 3′-substituents. A preliminary investigation using one of the obtained C1-symmetric BINOL products was used as an organocatalyst, exhibiting better enantioselectivity than the previously reported organocatalyst, for the asymmetric α-alkylation of amino esters.

As fluorescent probes, the small Stokes shift and ACQ effect limit the application of BINOL derivatives. Herein, a new series of BINOL derivatives were synthesized which could be turned from ACQ to AIE fluorophores by changing the electron withdrawing group. Among these compounds, BIN-COP exhibits an obvious AIE property with low cytotoxicity. The bioimaging performance indicated that the designed fluorophores could be successfully used for bioimaging.

A ratiometric BINOL-based fluorescent probe for Zn2+ detection was rationally designed and synthesized. Based on the excited-state intramolecular proton transfer (ESIPT) mechanisms, the probe exhibited a significant variation on emission wavele
