    • PURPOSE: Provided are optically active quinoline carboxylic acid derivatives, pharmaceutically acceptable salts thereof, solvates thereof, and a process for preparation thereof, which are useful for an antibacterial agent. CONSTITUTION: The optically active quinoline carboxylic acid derivatives are represented by the following formula(1), and contains optical activity-causing 4-aminomethyl-4-methyl-3 (Z)-alkoxyiminopyrrolidine substituents at the 7-position of the quinolone nuclei, their pharmaceutically acceptable salts, and their solvates. In the formula(1), Q is C-H, C-F, C-Cl or N; Y is H or NH2; R is a straight or branched alkyl group of Cl-C, an allyl group or a benzyl group, and * represents optically pure chiral carbon atom. Their preparation process comprises the steps of: condensing the quinolone nuclei-containing compound of formula(3), with the ketal compound of formula(2a), in the presence of an acid acceptor to give the optically active quinoline carboxylic acid derivative of formula(4); deketalizing the optically active quinoline carboxylic acid derivative of formula(4) to give the pyrrolidinone compound of formula(5); and reacting the pyrrolidinone compound of formula(5) with an alkoxylamine in the presence of a base to obtain the desired compound of formula(1).
