<p>Isoquinolines derivs. of formula (I) in their (R) and (S) forms, and mixtures of these, and their acid addn. salts, are new. In (I) R is straight or branched 1-10C alkyl. A typical prod. is 3- (3-methyl-5-isoquinolyl)imino 1,5,10,10a-tetrahydro thiazolo 3,4-b (S)-isoquinoline, m. pt. 181 degrees C. In an example this was pred. from 5-amino-3-methyl isoquinoline and 3-methylthio-1,5 10, 10a-tetrahydro thiazolo 3, 4-b S-isoquinolinium iodide in pyridine at 20 degrees C.</p> |
