CHIRAL 9,9 ' BINAPHTHO2,3-bFURANS

摘要

A series of novel difuro-fused binaphthalenes are reported. Synthetic methods include methylation, halogenation, Sonogashira coupling as well as base-mediated cyclization are employed to furnish the title compounds from chiral BINOL (R-BINOL and S-BINOL). The final products are confirmed by NMR spectra and mass spectra.
