Abstract

Process for preparing cyclic thioimidates of the general formula: ** (See formula) ** where R is defined as follows: (1) a thiophene residue, of formula: ** (See formula) ** where R1 is a hydrogen or chlorine atom, or a methyl group, and R2 is a hydrogen atom or a methyl group, n is 2 or 3, X is attached to position 2 or 3 of the thiophene core, and is a vinylene group, and is attached to the 2-position, and R2 to the 5-position, when X is attached to the 3-position, and R1 is attached to the 5-position, and R2 to the 3-position, when X is attached to the position 2; Y (2) 2-furyl, 3-methyl-2-furyl, 5-isothiazolyl, 4-methyl-5-isothiazolyl, 4-thiazolyl, 5-methyl-4-thiazolyl, 5-thiazolyl, 4-haloethyl-5-thiazolyl , 1-methyl-3-pyrazolyl, 1,4-dimethyl-5-pyrazolyl, 1-methyl-2-pyrrolyl, 1,3-dimethyl-2-pyrrolyl, 2-thiazolyl, phenyl, and 2-substituted phenyl, in wherein the substituent is chloro, bromo, iodo fluoro, nitro, hydroxy, methyl or ethyl, 3-substituted phenyl wherein the substituent is chloro, fluoro, iodo, bromo or hydroxy, 4-substituted phenyl wherein the substituent is chlorine, bromine, iodine, fluorine, hydroxy, methyl or ethyl; and where X is ethylene or vinylene, and n is 3; and the non-toxic acid addition salts of the foregoing, characterized by condensing a thiophenecarboxaldehyde, of the formula: R - CH = O where R is as defined in point 1, with 2-methylthiazoline or 2-methyl-dihydrothiazine.
