New mono-quaternized allyl bromide salts of bis-Cinchona alkaloid ligands, [(QD) 2 PHAL-Allyl]Br and [(QN) 2 PHAL-Allyl]Br, have been synthesized which can be converted into their highly water-soluble multihydroxylated derivatives under asymmetric dihydroxylation (AD) conditions and, thus, easily re
