ChiralP,N-ligands derivedfromquinoline and with a trans and cis cyclohexane backbone were easily synthesised in four steps fromquinoline N-oxide. The enantiopure trans isomer was obtained by the way of chiral resolution of the mixture of trans- and cis-2-(quinolin-2-yl)cyclohexanol with dibenzoyltartaric acid and then subjected to a Mitsunobu reaction and deprotection to give the corresponding
