  • Patent number: 4370482
    Abstract: A process for the manufacture of 1-(2-alkoxyethyl)-4-phenyl-4-imidazolin-2-ones, 1-(2-alkoxyethyl)-4-phenyl-2-imidazolidones, 1-(2-alkoxyethyl)-4-phenyl-imidazolidine-2-thiones, certain of the corresponding 1-(2-hydroxyethyl) derivatives, and their 3-acylated derivatives, and certain related compounds which are all useful as intermediates in a new process for the manufacture of the anthelmintic levamisole, (-)-2,3,5,6-tetrahydro-6-phenylimidazo-[2,1-b]thiazols, and its derivatives through conventional resolution procedures. The new process also permits the direct manufacture of optically active 1-(2-alkoxyethyl)-4-phenyl-2-imidazolidone and their 3-acylated derivatives, optically active 1-(2-alkoxyethyl)-4-phenylimidazolidine-2-thiones, and levamisole, the levorotatory isomer of tetramisole, using catalytic amounts of a chiral reducing agent, with the elimination of conventional resolution procedures.

  • Patent number: 4282225
    Abstract: Thiazole derivatives of general formula (I) ##STR1## in which n is 1 or 2 and Ar represents a phenyl radical unsubstituted or substituted by one or more substituents selected from halogen atoms, the radical CF.sub.3, the phenyl radical straight or branched chain alkyl radicals having 1 to 4 carbon atoms, and cycloalkyl radicals having 3 to 6 carbon atoms, and their pharmaceutically acceptable acid addition salts are useful in therapy as anti-depressive agents. They are prepared by reacting the thiazole ##STR2## with a ketone X--CH.sub.2 --CO--CH.sub.2 O--Ar (III) (X is a leaving group, such as halogen).
