We report here a simple and convenient route for the stereoselective synthesis of (R)-(-)- and (S)-(+)-homocitric acid lactones, which play very important roles in biochemistry. The method involves only three steps, starting from the readily available met

A method of combating plant-pathogenic bacteria, comprising applying to the bacteria or to a bacteria habitat a bactericidally effective amount of a cyclopropyl-1,4-dihydro-4-oxo-3-quinolinecarboxylic acid derivative of the formula STR1 in which A represents straight-chain or branched alkylene with 1 to 6 carbon atoms or a >C=CH-- radical, R1 represents alkoxycarbonyl with 1 to 6 carbon atoms in the alkyl part, benzyloxycarbonyl, carboxyl, optionally substituted carbamoyl, cyano or dialkoxyphosphonyl or alkylsulphonyl with 1 to 4 carbon atoms in the alkyl part, and R2 represents hydrogen, alkoxycarbonyl with 1 to 6 carbon atoms in the alkyl part, benzyloxycarbonyl, optionally substituted carbamoyl, cyano, chlorine, acetyl, alkyl with 1 to 3 carbon atoms or phenyl, or R1 and R2, together with the carbon atom which they substitute, can also form a 2-oxo-tetrahydrofuryl ring, R3, R4, R5 and R6 can be identical or different and represent hydrogen, methyl, ethyl or n- or i-propyl and X represents hydrogen, halogen or nitro, or an acid addition salt, alkali metal salt, alkaline earth metal salt, heavy metal salt or hydrate thereof. The heavy metal salts are new.
