A series of 18 regio- and stereo-chemically diverse chiral non-racemic 1,2-, 1,3-, and 1,4-diamines have been synthesized from commercial (1<i>S</i>)-(+)-ketopinic acid and (1<i>S</i>)-(+)-10-camphorsulfonic acid. The structures of the diamines are all based on the d-(+)-camphor scaffold and feature isomeric diversity in terms of regioisomeric attachment of the primary and the tertiary amine function and the <i>exo/endo</i>-isomerism. Diamines were transformed into the corresponding noncovalent ...[more]
