Abstract

Procedure for the preparation of 3,4-dihydro-2H-isoquinoline-1-thiones of the general formula **(See formula)** in which R1 and R2 each signify the same or different alcohol radicals, each with 1 to 6 carbon atoms or R1 signifies a phenylalkyl radical with 7 or 8 carbon atoms or a phenyl radical and at the same time R2 signifies hydrogen, a alcoholic or alcoholic radical with 1 to 6 carbon atoms, a carbon atom being able to be replaced by an oxygen or sulfur atom or it means a phenyl radical, being able to form R1 and R2 also, together with the carbon atom in position 4, a ring 5- or 6-membered saturated carbocyclic, R3 signifies hydrogen or an alkoxy group with 1 to 4 carbon atoms, and R4 signifies hydrogen or together with R3 the 6,7-oxymethylene group, and R5 signifies hydrogen or an alcohol radical with 1 to 4 6 carbon atoms, preferably with 1-4 carbon atoms, characterized in that a) it is subjected to cyclization by treatment with acid catalysts to compounds of the general formulas **(See formula)** wherein R1 to R5 have the above meanings and Y means an optionally substituted amino group, an O-alcohol or S-alcohol radical or an S-phenyl radical; or b) in compounds of the general formula III **(See formula)** the oxygen atom is replaced by sulfur in a manner known per se.
