The synthesis of the (+)-(R)-isomer of OPC-18790 has been published: The condensation of 6-hydroxyquinolin-2(1H)-one (I) with (S)-(+)-epichlorohydrin (II) by means of triethylamine in methanol gives (S)-(+)-6-(3-chloro-2-hydroxypropoxy)quinolin-2(1H)-one (III), which by reaction with KOH in isopropanol/water yields the (R)-(-)-epoxide (IV). Finally, this compound is condensed with 3,4-dimethoxybenzylamine (V) by heating its mixture at 80 C. The (+)-(R)-isomer is about 10-fold more potent than the (-)-(S)-isomer.
